    Full Text Available Little is known about companies whose core business is selling telecommunications products that lever open source projects. Open source telecommunications (OST companies operate in markets that are very different from typical software product markets. The telecommunications market is regulated, vertically integrated, and proprietary designs and special chips are widely used. For a telecommunications product to be useful, it must interact with both access network products and core network products. Due to specifications in Service Agreements Levels, penalties for failures of telecommunications products are very high. This article shares information that is not widely known, including a list of OST companies and the open source projects on which they depend, the size and diversity of venture capital investment in OST companies, the nature of the commercial product-open source software and company-project relationships, ways in which OST companies make money, benefits and risks of OST companies, and competition between OST companies. Analysis of this information provides insights into the ways in which companies can build business models around open source software. These findings will be of interest to entrepreneurs, top management teams of incumbent companies that sell telecommunications products, and those who care about Ontario's ability to compete globally.

    Ankri, R; Maroune, M-H

    2017-11-01

    West Africa still faces important public health issues today: improving the health infrastructure, compensating for the lack of medical personnel, and bringing the rural "lost-to-follow-up" population into an inclusive healthcare system. At the same time, the boom in the mobile telephone market is providing important business opportunities for telecommunications companies in this field, leading to the rapid propagation of eHealth solutions. Thus, the telecom companies' technical innovations enable the creation of digital health solutions adapted to the specific needs of the West African market. The companies can thus increase their business through eHealth and simultaneously generate positive externalities (a healthier population), meeting the goals of their corporate social responsibility policies. We will see how these companies, aware of this opportunity, build these solutions and they meet the challenges they will confront.

    Full Text Available Abstract The influence of globalization in telecommunication companies has greatly increased the level of competition in the industry and they are forced to be competitive to survive. Different types of strategies are put in place in order to be profitable and competitive. All these strategies are directed to attract, retain and maintain customers for continuous profitability. However, majority of them hardly measure the impact of their strategic innovation on their customers. The paper seeks to explore the influence of competitive strategies embarked upon by selected telecommunication companies in Nigeria on their performance. The paper also examines how competitive strategies could be implemented for improved customer satisfaction, retention and loyalty. Three null hypotheses were postulated to test the relationship between lower prices and customer satisfaction, uninterrupted trunk services and customer loyalty, and customer complaint handling and retention. Only customers using telephone service were selected as respondents from Lagos State. The state was stratified in to 20 local government council area and questionnaires were distributed to 125 respondents in each of them. The completion rate of the questionnaire in each of them is between 103 and 110. Survey research design was adopted to carry out the study. A structured questionnaire was designed and validated through the construct validity and tested for confirmation using the KMO measure of sampling adequacy. It was also made reliable using Cronbach’s Alpha test. From the study, findings revealed relationship between competitive strategies and customer satisfaction, retention and loyalty. The findings revealed that there is a relationship between competitive strategies, its constituents and performance of telecommunication companies. It is recommended that universal mobile telecommunication services (UMTS operators should adopt the culture of competitive strategies since it can

    Full Text Available No published work is available on work-life balance (WLB programs in Jordan. Drawing on the methodology of Critical Realism, interviews with ten senior managers, and case studies in two large telecommunication companies were undertaken. WLB practices had both similarities and differences from those in developed countries. WLB policy and practice was constructed within three main areas: social and cultural practices; financial practices; leave arrangements. In comparison with developed countries, social practices such as praying time, Hajj leave and Ramadan concessions reflected the culture and religion of Jordan as an Arabic, Islamic country. Flexible practices, such as compressed working and paternity leave did not exist. The absence of these practices was also linked to social and cultural factors, as well to levels of current economic development. However, part-time working was developed primarily to benefit employers, rather than employees, in contrast to most developed countries.Employers’ reasons for adopting WLB practices were the level of competition in the labour market, government regulations, social and culture norms of society, pressures from women in the workforce, and pressure from labour unions. Financial practices were linked to the competitive market, reflecting the need to retain well-qualified staff. Financial benefits including subsidized childcare, paid study leave, and family health insurance, were reported to have the strongest positive impact on organisational morale and staff retention.

    We report on the generation of single-photon pulses from a single InAs/InP quantum dot in telecommunication bands (1.3-1.55 μm: higher transmittance through an optical fiber). First we prepared InAs quantum dots on InP (0 0 1) substrates in a low-pressure MOCVD by using a so-called InP 'double-cap' procedure. The quantum dots have well-controlled photo emission wavelength in the telecommunication bands. We also developed a single-photon emitter in which quantum dots were embedded. Numerical simulation designed the emitter to realize efficient injection of the emitted photons into a single-mode optical fiber. Using a Hanbury-Brown and Twiss technique has proved that the photons through the fiber were single photons

    2014-02-01

    Full Text Available This paper is an application of Relevance Theory for the interpretation of short messaging service (SMS text messages emanating from Nigerian telecommunications companies to their subscribers. The aim of the research was to identify and describe the manipulative strategies employed by Nigerian telecommunications companies to induce subscribers to part with their money through sales promotion lotteries. 100 SMS texts were purposively extracted from the cell phones of randomly selected residents of Lagos Nigeria who had received promotional SMS text messages from three major Nigerian telecommunications companies. Using Sperber and Wilson's Relevance Theory (1995 as its theoretical framework, the paper described the manipulative use of SMS by Nigerian telecommunications companies. The analysis revealed that SMS text messages were encoded to achieve maximization of relevance through explicature and implicature; contextual implication and strengthening; and the reduction of processing effort through violating the maxim of truthfulness and the creative use of graphology. The paper concludes that SMS text-messages were used manipulatively by Nigerian telecommunications companies to earn indirect income from sales promotion lottery.

    Changes in industries and work practices have coincided with work-related musculoskeletal disorders (MSDs). This study was conducted to determine the prevalence of MSDs and to assess postural loading in assembly workers of an Iranian telecommunication manufacturing company. Data were collected from 193 randomly selected workers in 4 units of the company. The Nordic musculoskeletal disorders questionnaire and the UBC ergonomic checklist were used as data collection tools. Loading on the upper body assessment (LUBA) was used to assess postural loading. Lower back symptoms were the most prevalent problems among the workers (67.9%). LUBA showed that most assembly workers (94.3%) had experienced considerable and high postural loading (postural load index, PLI > 5). Regression analyses revealed that lighting, rotation, contact stress, repetition, gender and age were factors associated with symptoms. Work-related MSDs occurred at a high rate among workers. Postural loading requires consideration. Any ergonomic intervention should focus on eliminating ergonomic factors associated with symptoms.

    Full Text Available This study investigated the relationship between organizational imaginary and tacit dimension of knowledge creation, according to Nonaka and Takeuchi (1997 model, in a telecommunications company. This choice is justified because such segment is highly competitive and knowledge-intensive. Qualitative approach and case study strategy were used, based on documentary analysis, semi-structured interviews and application of projective techniques in workshops. The results showed that the lack of organizational intention concerning the collective commitment to knowledge creation, in a manner clearly articulated by senior management, fails to leverage the existing fertile grounds for innovation, having in view the spontaneous commitment shown by its employees with the image of the company, which is great in their point of view.

    2007-09-01

    Full Text Available This paper examines the discourse configurations on the environmental theme in business organizations and its relevance to the understanding of the inclusion of ecological discourses in the discourses of organizational members. A case study into a Brazilian telecommunications company offers empirical evidence. It begins with the understanding that organizations adopt several strategies in an attempt to disseminate a certain environmental discourse. As these efforts share space with other pressures, a fragmented discourse emerges. In this paper, the pressures of the environmental theme on organizations are discussed in order to understand this process. The second part of the argument focuses on the context of the case study – Brazilian organizations – and, afterwards, the third part deals with ecological discourses in their insertions in organizational interests. The data of the case study were collected through documental research and 40 semi-structured interviews. The analysis was applied based on Discourse Analysis. In conclusion, an ambiguous discourse configuration was shown that offer elements for the understanding that philanthropy, legal obligation and organizational competitiveness need to be used together to offer legitimacy to the theme of environmental responsibility in business organizations.

    2015-03-16

    We investigated the photoluminescence of individual air-suspended single-walled carbon nanotubes (SWNTs) from 6 to 300 K. Time-resolved and antibunching measurements over the telecommunication wavelength range were performed using a superconducting single-photon detector. We detected moderate temperature independent antibunching behavior over the whole temperature range studied. To investigate the exciton dynamics, which is responsible for the antibunching behavior, we measured excitation-power and temperature dependence of the photoluminescence spectra and lifetime decay curves. These measurements suggested an exciton confinement effect that is likely caused by high-dielectric amorphous carbon surrounding the SWNTs. These results indicate that SWNTs are good candidates for light sources in quantum communication technologies operating in the telecommunication wavelength range and at room temperature.

    The relationship between workplace factors and work-related upper extremity musculoskeletal disorders (UE disorders) was assessed in a cross-sectional study of 533 telecommunication employees utilizing video display terminals (VDTs). Cases of UE disorders were defined using symptom questionnaires and physical examinations. Data on demographics, individual factors (medical conditions and recreational activities), work organization and practices, and psychosocial aspects of work, including electronic performance monitoring (EPM), were obtained by questionnaire. Associations between workplace factors and UE disorders were assessed by multiple logistic models generated for each of the four UE areas (neck, shoulder, elbow, hand/wrists). One-hundred and eleven (22%) participants met our case definition for UE disorders. Probable tendon-related disorders were the most common (15% of participants). Probable nerve entrapment syndromes were found in 4% of participants. The hand/wrist was the area most affected, 12% of participants. The following variables had associations in the final models (p < 0.05) with at least one of the four UE disorders, although the strength of these associations were modest. Non-white race, a diagnosis of a thyroid condition (self-reported) use of bifocals at work, and seven psychosocial variables (fear of being replaced by computers, increasing work pressure, surges in workload, routine work lacking decision-making opportunities, high information processing demands, jobs which required a variety of tasks and lack of a production standard) were associated with UE disorders. This study indicates that work-related UE musculoskeletal disorders are relatively common among telecommunication workers who use VDTs, and adds to the evidence that the psychosocial work environment is related to the occurrence of these disorders.

In order to ensure success of an organisation, it is important to look for new investment solutions helping companies to develop individualized and differentiated ways of interaction with customers, ensuring their loyalty and allowing to maintain competitiveness in the market. More and more often, customer relationship management systems are chosen to achieve these aims. These systems are applied for business to efficiently manage relations with customers of a company; they help increasing the benefit obtained by every supplier or customer to the maximum and improving the results of the entire activity. Due to the increase in the number of organisations implementing customer relationship management systems (CRM, it is becoming important to study and evaluate these technologies and their influence. This would help to better understand the present problems related with customer relationship management (CRM systems.

    Anisotropic Rabi oscillation in the exciton state in a single InAs/GaAs quantum dot (QD) was demonstrated in the telecommunication-band by selecting two orthogonal polarization angles of the excitation laser. Our InAs QDs were embedded in an intrinsic layer of an n-i-Schottky diode, which provides an electric field to extract photoexcited carriers from QDs. Owing to the potential anisotropy of QDs, the fine structure splitting (FSS) energy in the exciton state in single InAs QDs was ˜110 μeV, measured by polarization-resolved photocurrent spectroscopy. The ratio between two different Rabi frequencies, which reflect anisotropic dipole moments of two orthogonal exciton states, was estimated to be ˜1.2. This demonstrates that the selective control of two orthogonal polarized exciton states is a promising technique for exciton-based-quantum information devices compatible with fiber optics.

    Full Text Available The main objective of this research is to analyze the impacts that re-structuring the telephone operators at the cellular operators has on the identity of the workers. The theme talks about the profound transformations which occur in the world of work, derived from the link between globalization and the economy, the ongoing advancements in technology and the new immerging forms of Company management. The methodology adopted is of qualitative nature whose data was collected by means of semi-structured interviews. Theoretically speaking, this research boarders two fundamental themes; the current changes that occur in relationships at the workplace and the effects these changes have on the identity of professionals. The survey results show that the process of organizational restructuring culminated with the simultaneous resignation of 382 officials from the area of call center and was conducted in a cruel and merciless. The managers were informed of the decision by the company two days before the action occurredand the area of human resources was limited to bureaucratic aspects of care. The experience generated by the interviewees feelings of surprise, disappointment, sadness and anguish, affecting negatively the process of construction and reconstruction of identities.

    Full Text Available Parallel Discrete Event Simulation (PDES with the conservative synchronization method can be efficiently used for the performance analysis of telecommunication systems because of their good lookahead properties. For PDES, a cost effective execution platform may be built by using single board computers (SBCs, which offer relatively high computation capacity compared to their price or power consumption and especially to the space they take up. A benchmarking method is proposed and its operation is demonstrated by benchmarking ten different SBCs, namely Banana Pi, Beaglebone Black, Cubieboard2, Odroid-C1+, Odroid-U3+, Odroid-XU3 Lite, Orange Pi Plus, Radxa Rock Lite, Raspberry Pi Model B+, and Raspberry Pi 2 Model B+. Their benchmarking results are compared to find out which one should be used for building a mini supercomputer for parallel discrete-event simulation of telecommunication systems. The SBCs are also used to build a heterogeneous cluster and the performance of the cluster is tested, too.

    2013-01-01

    Important technological steps are discussed and realized for future room-temperature operation of III-nitride single photon emitters. First, the growth technology of positioned single pyramidal InN nanostructures capped by Mg-doped GaN is presented. The optimization of their optical characteristics towards narrowband emission in the telecommunication wavelength range is demonstrated. In addition, a device concept and technology was developed so that the nanostructures became singularly addressable. It was found that the nanopyramids emit in the telecommunication wavelength range if their size is chosen appropriately. A p-GaN contacting layer was successfully produced as a cap to the InN pyramids and the top p-contact was achievable using an intrinsically conductive polymer PEDOT:PSS, allowing a 25% increase in light transmittance compared to standard Ni/Au contact technology. Single nanopyramids were successfully integrated into a high-frequency device layout. These decisive technology steps provide a promising route to electrically driven and room-temperature operating InN based single photon emitters in the telecommunication wavelength range. (paper)

  4. Job Characteristics and Their Implications on the Satisfaction Levels of Call Center Employees: a study on a large telecommunications company

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available Standardization of answers and cost reduction efforts have provided a specific relevance to call centers in the commercial strategy of many service companies. The aim of this research is to analyze to what extent job characteristics, as identified by Hackman and Oldham (1980, are essential determinants for the level of satisfaction of the contact employee in a call center. Indeed, literature clearly suggests that job characteristics have a huge influence on employees´ work performance, their level of satisfaction, and, as a consequence, on the quality of services provided to the customers. In order to answer these questions, we have performed a case study, based on a questionnaire survey. Findings reveal that employees feel that their jobs are highly structured and that they are being closely monitored, what might worsen their performance regarding the contact with the customer, mainly in what concerns customization, flexibility and adequate answer in a single contact. In order to increase frontline employees’ performance, a proposal that enhances job autonomy and values intrinsic satisfaction is made. The research suggests the need to change the way companies view contact employee’s job, in a call center context, not always perceived and designed as strategic or determinant for customers’ satisfaction, which calls for additional institutional investment in the redesign of such job.

    Two wind-diesel generating stations have been installed at telecommunication towers in the remote communities of Kuujjuarapik and Lac Julien in northern Quebec. The use of wind power contributes to the sustainable development in these remote areas by lowering the reliance on costly helicopter-transported diesel fuel and by reducing the release of greenhouse gases to the atmosphere. The technical characteristics of the Bergey 100 kW turbine with battery charger were presented along with the technical characteristics of the EolDie control panel that controls the supply of electricity from either the wind or diesel power generators. For the first time, the ATI-Wind technology system that was installed can supply the needs of the large telecommunication towers of Bell Canada and Telebec from either the wind or the diesel generators. The system is also capable of shutting down the diesel generators when wind energy is sufficient to take over. Early results from June 2005 showed that the diesel generators could be turned off for 55 per cent of the time. Preliminary results of these 2 projects were discussed by the firms in charge of the diesel and wind aspects and recommendations for improvements to the control systems were presented. 11 figs.

    2016-11-01

    InGaAsP/InP-air-aperture micropillar cavities are proposed to serve as 1.55-μm single photon sources, which are indispensable in silica-fiber based quantum information processing. Owing to air-apertures introduced to InP layers, and adiabatically tapered distributed Bragg-reflector structures used in the central cavity layers, the pillar diameters can be less than 1 μm, achieving mode volume as small as (λ/n)3, and the quality factors are more than 104 - 105, sufficient to increase the quantum dot emission rate for 100 times and create strong coupling between the optical mode and the 1.55- μm InAs/InP quantum dot emitter. The mode wavelengths and quality factors are found weakly changing with the cavity size and the deviation from the ideal shape, indicating the robustness against the imperfection of the fabrication technique. The fabrication, simply epitaxial growth, dry and chemical etching, is a damage-free and monolithic process, which is advantageous over previous hybrid cavities. The above properties satisfy the requirements of efficient, photonindistinguishable and coherent 1.55-μm quantum dot single photon sources, so the proposed InGaAsP/InP-air-aperture micropillar cavities are prospective candidates for quantum information devices at telecommunication band.

    2006-01-01

    We report on our progress in development of superconducting single-photon detectors (SSPDs), specifically designed for secure high-speed quantum communications. The SSPDs consist of NbN-based meander nanostructures and operate at liquid helium temperatures. In general, our devices are capable of GHz-rate photon counting in a spectral range from visible light to mid-infrared. The device jitter is 18 ps and dark counts can reach negligibly small levels. The quantum efficiency (QE) of our best SSPDs for visible-light photons approaches a saturation level of ∼30-40%, which is limited by the NbN film absorption. For the infrared range (1.55μm), QE is ∼6% at 4.2 K, but it can be significantly improved by reduction of the operation temperature to the 2-K level, when QE reaches ∼20% for 1.55-μm photons. In order to further enhance the SSPD efficiency at the wavelength of 1.55 μm, we have integrated our detectors with optical cavities, aiming to increase the effective interaction of the photon with the superconducting meander and, therefore, increase the QE. A successful effort was made to fabricate an advanced SSPD structure with an optical microcavity optimized for absorption of 1.55 μm photons. The design consisted of a quarter-wave dielectric layer, combined with a metallic mirror. Early tests performed on relatively low-QE devices integrated with microcavities, showed that the QE value at the resonator maximum (1.55-μm wavelength) was of the factor 3-to-4 higher than that for a nonresonant SSPD. Independently, we have successfully coupled our SSPDs to single-mode optical fibers. The completed receivers, inserted into a liquid-helium transport dewar, reached ∼1% system QE for 1.55 μm photons. The SSPD receivers that are fiber-coupled and, simultaneously, integrated with resonators are expected to be the ultimate photon counters for optical quantum communications

The company had completed a preliminary design of the jet but needed analyses and testing to proceed with detailed design and subsequent fabrication of a prototype aircraft. NASA Lewis Research Center used computational fluid dynamics (CFD) analyses to ferret out areas of excessive curvature in the inlet where separation might occur. A preliminary look at the results indicated very good inlet performance; and additional calculations, performed with vortex generators installed in the inlet, led to even better results. When it was initially determined that the airflow distortion pattern at the compressor face fell outside of the limits set by the engine manufacturer, the Lewis team studied possible solutions, selected the best, and provided recommendations. CFD results for the inlet system were so good that wind tunnel tests were unnecessary.

    Full Text Available Objetive: This study was carried out in order to know the comportment of the median nerve’s impulse speed at the carpal tunnel associated to the exposure time to the fingers’ repetitive motion risk factor. Methodology: This study was applied to data-entry personnel at two companies in the city of Medellin, Colombia, during October and November of 2005. Age, gender, labour exposure time, dominant hand and pathological antecedents associated to the carpal tunnel syndrome variables were investigated. Clinical test and a median nerve conduction test were applied to the workers. Discussion: 55 data-entry workers were evaluated, for a total of 110 hands. The survey included ages between 19 and 40 years old and an average age of 28; 86% of the studied subjects were women; 91% of surveyed subjects declared themselves as right-handed and 60% had a normal weight. Subjects had worked between 12 and 180 months as data-entry personnel with an average time of 83 months, working 48 hours a week. No relevant statistical link was found between labour exposure time and median nerve conduction. Results suggest that doing repetitive movements at work as the only risk factor is not a cause of nerve conduction disorder in the median nerve.

    Full Text Available The author concerns the current state and possible ways of telecommunication sector of the Russian economy development in the conditions of world economy globalization and suggests that the process of globalization reflects the current stage of telecommunication companies’ capital internationalization. The analysis of telecommunication sector shows that it is not only a perspective, highmargin and dynamically developing sector but is still one of the most integrated into the system of world economic relations. The stages of Russian telecommunication companies’ capital internationalization are determined, the internal connections between internationalization process and globalization are revealed. It is revealed that the new information and communication technologies development and expansion results in substantial increase in cooperation between economical entities and provides a sustainable long-term economical growth of telecommunication enterprises. The financial and operational data determining the effectiveness of telecommunication companies’ activity are presented. The analysis of tendencies promoting the extension of the market activity of Russian telecommunication companies at global information and telecommunication infrastructure shows that the main tendencies are the following ones: foreign capital inflow increase, capital integration and expansion of new services based on technologies convergence. The author reasonably concludes in recent times, the telecommunication sector of the Russian economy formation and development is determined by the existing global trends.

Inicialmente, são discutidos os cuidados e a importância do contrato de terceirização, segundo abordagem da economia dos custos de transação. Analisam-se as possíveis causas das falhas na contratação, e sugerem-se providências para evitar repetições em implementações semelhantes. A experiência adquirida indica que um erro primordial, na opinião dos autores, refere-se à falta de definição da estratégia a ser seguida pela organização em relação ao modelo de contratação. Essa definição é uma etapa fundamental, já que o contrato deve estar alinhado à estratégia.This article examines, through the technique of case study, the process of logistics outsourcing in a Brazilian telecommunications company. Initially, the importance of contracts for outsourcing is analyzed according to the perspective of the transaction costs economics theory. The possible causes of imperfections in the contracting process are analyzed, and the steps to avoid the repetition of these mistakes in similar implementations are suggested. According to the authors' point of view, the acquired experience indicates that a primary error in outsourcing contracts refers to the lack of a strategy to be followed by the organization in relation to a contracting model. This definition is a fundamental step, since the contract must be aligned to the strategy.

    As in other industrial sectors, Japanese telecommunications organizations export significantly more products than they import, even when substantial cost-savings can be realized. One example is optical fibers, which some Japanese service companies do not buy from outside suppliers who have taken advantage of economies of scale. Nippon Telephone and Telegraph, until recently a common carrier, is meeting increasing competition from newly-formed indigenous telecommunications subsidiaries who are taking advantage of fiber optics and microwave communications capabilities. Various cooperative projects with U.S. companies are described, noting the tendency of Japanese manufacturers to cease relationships with U.S. companies when Japanese products become competitive and also the necessity of U.S. firms to gain political cooperation from the Japanese government in order to make sales in Japan.

    The Office of Civilian Radioactive Waste Management (OCRWM) must, among other things, be equipped to readily produce, file, store, access, retrieve, and transfer a wide variety of technical and institutional data and information. The data and information regularly produced by members of the OCRWM Program supports, and will continue to support, a wide range of program activities. Some of the more important of these information communication-related activities include: supporting the preparation, submittal, and review of a license application to the Nuclear Regulatory Commission (NRC) to authorize the construction of a geologic repository; responding to requests for information from parties affected by and/or interested in the program; and providing evidence of compliance with all relevant Federal, State, local, and Indian Tribe regulations, statutes, and/or treaties. The OCRWM Telecommunications Network Plan (TNP) is intended to identify, as well as to present the current strategy for satisfying, the telecommunications requirements of the civilian radioactive waste management program. The TNP will set forth the plan for integrating OCRWM's information resources among major program sites. Specifically, this plan will introduce a telecommunications network designed to establish communication linkages across the program's Washington, DC; Chicago, Illinois; and Las Vegas, Nevada, sites. The linkages across these and associated sites will comprise Phase I of the proposed OCRWM telecommunications network. The second phase will focus on the modification and expansion of the Phase I network to fully accommodate access to the OCRWM Licensing Support System (LSS). The primary components of the proposed OCRWM telecommunications network include local area networks; extended local area networks; and remote extended (wide) area networks. 10 refs., 6 figs

    2016-07-01

    Full Text Available The relationship between telecommunications infrastructure and economic activity is under discussion in many scientific papers. Most of the authors use for research and analysis the Jipp curve. A lot of doubts about the correctness of the Jipp curve appear in terms of applying econometric models. The aim of this study is a review of the Jipp curve, refining the possibility of its application in modern conditions. The methodology used in the study is based on dynamic econometric models, including tests for nonstationarity and tests for causality. The focus of this study is directed to methodological problems in measuring the local density types of telecommunication networks. This study offers a specific methodology for assessing the Jipp law, through VAR-approach and Granger causality tests. It is proved that mechanical substitution of momentary aggregated variables (such as the number of subscribers of a telecommunication network at the end of the year and periodically aggregated variables (such as GDP per capita in the Jipp�s curve is methodologically wrong. Researchers have to reconsider the relationship set in the Jipp�s curve by including additional variables that characterize the Telecommunications sector and the economic activity in a particular country within a specified time period. GDP per capita should not be regarded as a single factor for the local density of telecommunications infrastructure. New econometric models studying the relationship between the investments in telecommunications infrastructure and economic development may be not only linear regression models, but also other econometric models. New econometric models should be proposed after testing and validating with sound economic theory and econometric methodology.

    After years of waiting for Picture Archiving and Communication Systems (PACS) to become technologically mature and readily available at competitive costs, it appears that the ingredients are now available for producing at least the telecommunication component of the PACS. They are as follows: 1. A variety of pathways now exist for long-distance high-speed digital data transmission at acceptable costs. 2. Developments in computer technology and keen competition in the microcomputer and video display markets have markedly reduced to costs for components of digital data terminals. 3. The volume of native digitally acquired images is expanding yearly, whereas at the same time the pressure for converting images acquired in analog format to digital format is increasing. 4. The advantages of and potential for processing and storing imaging data in digital format are becoming more widely recognized. These factors, individually and collectively, favor the successful applications of image telecommunication to the field of diagnostic imaging. The authors have attempted to provide an overview of the subject and the basics of this emerging technology

    Full Text Available The concept of Single Member Company (the “SMC” was introduced in Company law of Pakistan in 2002. However, besides having created anomalies within the existing legislation that have already been analyzed by different academics, there remains potential for abuse of the concept of separate legal entity and/or the doctrine of limited liability at the hand of the single member of the SMC. In this view of matter, this article proposes to review the Section 160 of Companies Ordinance, 1984 to argue that there is no provision in the law in Pakistan to effectively place a mechanism of checks and balances so as to reduce the risk of escaping the corporate liability by the SMC in Pakistan. In the same context, this article also dilates upon the inadequacies of SMC legislation in relation to the concept of social, economic and environmental responsibilities of corporate entities.

    Ion implantation proved to be a universal technique for producing waveguides in most optical materials. Tellurite glasses are good hosts of rare-earth elements for the development of fibre and integrated optical amplifiers and lasers covering all the main telecommunication bands. Er{sup 3+}-doped tellurite glasses are good candidates for the fabrication of broadband amplifiers in wavelength division multiplexing around 1.55 μm, as they exhibit large stimulated cross sections and broad emission bandwidth. Fabrication of channel waveguides in such a material via N{sup +} ion implantation was reported recently. Sillenite type Bismuth Germanate (BGO) crystals are good nonlinear optical materials. Parameters of waveguide fabrication in both materials via implantation of MeV-energy N{sup +} ions were optimized. First single-energy implantations at 3.5 MeV at various fluences were applied. Waveguide operation up to 1.5 μm was observed in both materials. Then double-energy implantations at a fixed upper energy of 3.5 MeV and lower energies between 2.5 and 3.1 MeV were performed to suppress leaky modes by increasing barrier width. Improvement of waveguide characteristics was found by m-line spectroscopy and spectroscopic ellipsometry.

  9. Software Development Process Changes in the Telecommunications Industry

    Directory of Open Access Journals (Sweden)

    John Kevin Doyle

    2006-06-01

    Full Text Available The tremendous changes in the telecommunications business in the last several years drove changes in the software development processes of telecommunications equipment providers. We compare changes in these very large projects, in two companies, with those proposed in the Theory of Constraints / Critical Chains, Extreme Programming, and Agile development models. The 2000s have been a time of significant challenge in the telecommunications equipment business. Telecommunications service providers have excess equipment capacity. Many are waiting for next generation telephone switches that will simultaneously lower operating costs and enable additional revenue generation. The large service providers have drastically reduced their capital and expense purchases. Many small service providers, particularly the dot-coms, went bankrupt; much of their equipment is on the secondary market, at a fraction of the original cost. Thus the equipment market has significantly shrunk, and the equipment providers have been reducing expenses, while continuing to deliver software and hardware equipment at the high quality level required by the service providers. This drove many changes in the software development process. While the process changes are reported in two telecommunication equipment development organizations, the changes are applicable in any product development organization.

    This statement shortly describes the changes in the telecommunication market that have taken place in the last 12 years, during the socio-economical transformation in Poland. It concerns economical, legal and technical problems related to the development of the telecommunications in Poland based on the principles of the market economy. Especially it is related to the commercialization of this sector, what has been a result of the changes of the principal law ruling the national economy including changes ot the telecommunication law. Changes of the law enabled the creation of the commercial company Polish Telecom and opened the way to the privatization of this company. Due to the changed law the way to the step-by-step liberalization and de-monopolization process has been also opened in Poland. It has caused fully digital modernization of telecommunication network, introduction new services such as cellular communications and Internet services, as well as rapid development of the market, what has expressed in multiplication of number of subscribers of stationary telephony, creation of the big cellular market and new increasing Internet market. The statemnet also refers to present difficulties in development of this market and as well as to the prospects for the future developments.

    1994-11-01

    New federal standards for the protection of sensitive data now make it possible to ensure the authenticity, integrity and confidentiality of digital products, and non-repudiation of digital telecommunications. Under review and comment since 1991, the new Federal standards were confirmed this year and provide standard means for the protection of voice and data communications from accidental and wilful abuse. The standards are initially tailored to protect only `sensitive-but-unclassified' (SBU) data in compliance with the Computer Security Act of 1987. These data represent the majority of transactions in electronic commerce, including sensitive procurement information, trade secrets, financial data, product definitions, and company-proprietary information classified as `intellectual property.' Harmonization of the new standards with international requirements is in progress. In the United States, the confirmation of the basic standards marks the beginning of a long-range program to assure discretionary and mandatory access controls to digital resources. Upwards compatibility into the classified domain with multi-level security is a core requirement of the National Information Infrastructure. In this report we review the powerful capabilities of standard Public-Key-Cryptology, the availability of commercial and Federal products for data protection, and make recommendations for their cost-effective use to assure reliable telecommunications and process controls.

    2002-12-15

    These lectures throw a spotlight on different aspects of the evolution of telecommunications networks, namely on the various facets of service and network convergence. The last years progress in data and telecommunications technologies, such as P-based networks, and the enormous potential of mobile communication systems and users' demands for comprehensive and network-independent have led to a convergence of data and telecommunications infrastructures in many aspects. In order to help the reader to an easier understanding of the phenomenon convergence, in the first two parts of this volume the evolution of the basic technologies is described one by one. This is done briefly and is focused on the principle topics, just to build a basis for the third part devoted to problems of convergence in telecommunications. These notes are addressed to those readers, who in a quick overview want to be informed on the future service and network landscape. The notes are equally suited for professionals with the desire to extend their horizon as well as for students looking for an introduction into telecommunications under more general aspects. The authors clearly understand the difficulties in writing a book devoted to the evolution in telecommunications. Today, telecom landscape varies at very high speed. Every few months new network technologies, new products and new services are developed. Attempts to present them in time can be accessible only for magazine publications or contributions to conferences. Therefore, in a number of areas, such as Voice over IP and new switching technologies not much more than the starting point of new paradigms is described. However, the content is up-to-date to a degree, that the phenomenon convergence can be fully understood. Partially, these notes are based on a number of lecture courses that were delivered during recent ICTP winter schools devoted to multimedia and digital communications.

    Morris, B. [Electricity Association, London (United Kingdom)

    1996-08-01

    The role that telecommunications is likely to play in the future in the electricity markets of the U.K. following privatization beginning in 1990, and subsequent periods of massive restructuring, refocusing, diversification, and large scale mergers and takeovers. The current structure of the industry, the operation of the electricity market, the role of the regulator, the influence of the new trading environment, and the ways in which telecommunications is being used by individual companies, were reviewed. The general conclusion was that telecommunications will be a significant contributor to the success of the generation, transmission and distribution functions of the industry. It was predicted that the majority of companies will not choose to provide their own telecommunications needs. Reliance on third party `call centre services` providers might be a more frequently taken route, forced by scarcity of capital and in-house expertise. 3 figs.

    Full Text Available The opening of the telecommunications market is acceleration due to the world trends of deregulation and privatization under the WTO basic telecommunications agreements. Diversification of services and fast and efficient equipment procurement are becoming necessary conditions for the survival of telecommunications operators. However, the issue here is that telecommunications operators are still bound by the GPA (Government Procurement Agreement based on conditions of monopoly even though the procurement market in Korean is open substantially since 1997. Under such conditions, the continued application of the GPA on telecommunications operator who is highly competitive may result in a negative impact on the telecommunications business and quality of telecommunications service by undermining the autonomy of operator and decreasing operator’s procurement competitiveness. Therefore, this study examines the GPA and the issues raised by the agreement, and also attempts to suggest revisions or means of abrogating the unfair GPA with regards to the development and deregulation of the telecommunications business.

    Maria Augusta Soares Machado

    2015-03-01

    Full Text Available This paper presents a practical proposition for the application of the Linear Programming quantitative method in order to assist planning and control of customer circuit delivery activities in telecommunications companies working with the corporative market. Based upon data provided for by a telecom company operating in Brazil, the Linear Programming method was employed for one of the classical problems of determining the optimum mix of production quantities for a set of five products of that company: Private Telephone Network, Internet Network, Intranet Network, Low Speed Data Network, and High Speed Data Network, in face of several limitations of the productive resources, seeking to maximize the company’s monthly revenue. By fitting the production data available into a primary model, observation was made as to what number of monthly activations for each product would be mostly optimized in order to achieve maximum revenues in the company. The final delivery of a complete network was not observed but the delivery of the circuits that make it up, and this was a limiting factor for the study herein, which, however, brings an innovative proposition for the planning of private telecommunications network provisioning.

    A model is proposed along with empirical investigation to prove the existence of network effects in China's mobile telecommunications market. Futhernore, network effects on China's mobile telecommunications are estimated with a dynamic model. The structural parameters are identified from regression coefficients and the results are analyzed and compared with another literature. Data and estimation issues are also discussed. Conclusions are drawn that network effects are significant in China's mobile telecommunications market, and that ignoring network effects leads to bad policy making.

  20. Increased incidence of malignant melanoma of the skin in workers in a telecommunications industry.

    De Guire, L; Theriault, G; Iturra, H; Provencher, S; Cyr, D; Case, B W

    1988-12-01

    In 1982 physicians at a hospital melanoma clinic in Montreal noticed that among their patients there had been seven men working in a single telecommunications company. This raised suspicions that working in that industry might be associated with development of malignant melanoma of the skin (MMS). A preliminary gross comparison with general population rates indicated that there was an increased risk in this working group. To estimate the risk of MMS more accurately, a standardised incidence ratio (SIR) was calculated based on the rates of MMS in the local population of the Greater Metropolitan Montreal Area for the years 1976-83. During that period, among workers in all plants for the company, 10 male cases of MMS were observed for an expected number of 3.7 (SIR = 2.7; 95% CI = 1.31-5.02). No cases were observed among female workers (expected = 1.3). The excess was significant among cases with a short latency (less than 20 years since beginning of employment). There was no apparent pattern of exposure based on job titles or departments.

  6. Generation of optical frequencies out of the frequency comb of a femtosecond laser for DWDM telecommunication

    International Nuclear Information System (INIS)

    Kim, Y-J; Chun, B J; Kim, Y; Hyun, S; Kim, S-W

    2010-01-01

    We exploit the frequency comb of a fs laser as the frequency ruler to generate reference optical frequencies for multi-channel DWDM (dense wavelength-division-multiplexing) telecommunication. Our fiber-based scheme of single-mode extraction enables on-demand generation of optical frequencies within the telecommunication band with an absolute frequency uncertainty of 9.1×10 -13 . The linewidth of extracted optical modes is less than 1 Hz, and the instability is measured 2.3×10 -15 at 10 s averaging. This outstanding performance of optical frequency generation would lead to a drastic improvement of the spectral efficiency for the next-generation DWDM telecommunication

    Modern telecommunications rely on the transmission and manipulation of optical signals. Optical amplification plays a vital part in this technology, as all components in a real telecommunications system produce some loss. The two main issues with present amplifiers, which rely on erbium ions in a glass matrix, are the difficulty in integration onto a single substrate and the need of high pump power densities to produce gain. Here we show a potential organic optical amplifier material that demonstrates population inversion when pumped from above using low-power visible light. This system is integrated into an organic light-emitting diode demonstrating that electrical pumping can be achieved. This opens the possibility of direct electrically driven optical amplifiers and optical circuits. Our results provide an alternative approach to producing low-cost integrated optics that is compatible with existing silicon photonics and a different route to an effective integrated optics technology.

  20. High school science teachers' perceptions of telecommunications utilizing a Concerns-Based Adoption Model (CBAM)

    Science.gov (United States)

    Slough, Scott Wayne

    The purpose of this study was to describe high school science teachers' perceptions of telecommunications. The data were collected through open-ended ethnographic interviews with 24 high school science teachers from five different high schools in a single suburban school district who had been in an emerging telecommunications-rich environment for two and one-half years. The interview protocol was adapted from Honey and Henriquez (1993), with the Concerns-Based Adoption Model (CBAM) (Bailey & Palsha, 1992) providing a conceptual framework for data analysis. For this study, the emerging telecommunications-rich environment included a district-wide infrastructure that had been in place for two and one-half years that included a secure district-wide Intranet, 24 network connections in each classroom, full Internet access from the network, four computers per classroom, and a variety of formal and informal professional development opportunities for teachers. Categories of results discussed include: (a) teacher's profession use of telecommuunications; (b) teachers' perceptions of student's use of telecommunications; (c) teachers' perceptions of barriers to the implementation of telecommunications; (d) teachers' perceptions of supporting conditions for the implementation of telecommunications; (e) teachers' perceptions of the effect of telecommunications on high school science instruction; (f) teachers' perceptions of the effect of telecommunications on student's learning in high school science; and (g) the demographic variables of the sex of the teacher, years of teaching experience, school assignment within the district, course assignment(s), and academic preparation. Implications discussed include: (a) telecommunications can be implemented successfully in a variety of high school science classrooms with adequate infrastructure support and sufficient professional development opportunities, including in classes taught by females and teachers who were not previously

    Harrison, P; Schenk, D

    1993-11-01

    Right now, managed care is a vast cosmic soup. But whether its ultimate form is the result of a bureaucratic big bang or a series of small industry explosions, one thing seems clear: telecommunications is the framework upon which managed care will be built. Managed care's primary players--purchasers, providers and payors--have already discovered the unifying power of telecommunications within their respective worlds. However, as the three worlds collide, an entirely new set of special telecommunications needs arises. And most of these needs can be distilled into three basic requirements: bigger networks, faster networks and smarter networks.

  16. Arbitrarily high super-resolving phase measurements at telecommunication wavelengths

    International Nuclear Information System (INIS)

    Kothe, Christian; Bjoerk, Gunnar; Bourennane, Mohamed

    2010-01-01

    We present two experiments that achieve phase super-resolution at telecommunication wavelengths. One of the experiments is realized in the space domain and the other is realized in the time domain. Both experiments show high visibility and are performed with standard lasers and single-photon detectors. The first experiment uses six-photon coincidences, whereas the latter experiment needs no coincidence measurements, is easy to perform, and achieves, in principle, arbitrarily high phase super-resolution. Here, we demonstrate a 30-fold increase of the resolution. We stress that neither entanglement nor joint detection is needed in these experiments, which demonstrates that neither is necessary to achieve phase super-resolution.

  17. Restructuring the US telecommunications industry - Impact on innovation

    Science.gov (United States)

    Agnew, C. E.; Romeo, A. A.

    1981-01-01

    The Communications Act of 1934, which regulates the United States telecommunications industry, is becoming less able to deal with the changes brought by modern technology. Therefore, proposals are being made to restructure the industry. Breaking up AT&T into smaller firms would have only minor effects, since its ratio of R and D to sales has been near the median for large telephone companies. Restructuring AT&T into subsidiaries dealing at arms' length might cause a reordering of priorities toward more directly marketable and useful products, but too extensive a break-up could endanger Bell Labs' commitment to basic research. Regulation leads a firm to ignore true social value of possible products, expand into low profit markets, and favor capital-intensive over labor-intensive innovation. If regulatory lag occurs, a firm will produce cost-reducing innovation in order to increase its profit.

  18. Telecommunications: international opportunities for power utilities

    Energy Technology Data Exchange (ETDEWEB)

    Lewis, A. [Teleglobe Canada, Ottawa, ON (Canada)

    1996-08-01

    International telecommunications services markets and trends were reviewed in an effort to identify business opportunities for Canadian power utilities. With increasing deregulation in the U.S. and Canada, and other countries around the globe, market opportunities are beginning to open up. In monopoly markets opportunities exist in providing dual infrastructures to upgrade both the power delivery services (frequently poor), and telecommunications. Billing, collection and customer service expertise might be other marketable commodities, perhaps packaged as part of a network provision project as a service to existing power and telecommunications service providers. In countries with directed competition markets local partnerships may be the only vehicle for entering the market. In managed competition markets opportunities were said to exist in cellular radio technology, as well as in switched telephone service, local, long distance, or international. In general, opportunities outside telecommunications-rich North America were considered to have better potential, due to rapid deregulation and higher current growth rates in telecommunications. Careful examination and research of the political and business environment prior to entering any of the potentially fertile areas was advised.

  1. Substituting telecommunications for travel - Feasible or desirable

    Science.gov (United States)

    Van Vleck, E. M.

    1974-01-01

    This paper reviews recent advances in telecommunications and examines the detailed structure of travel to estimate the feasibility of substituting telecommunications for various travel objectives. The impact of travel is analyzed from a social, economic, energy, and pollution standpoint to assess the desirability of substitution. Perhaps 35-50% of the nation's travel could, in theory, be replaced by very advanced telecommunications (such as a much improved large-screen teleconferencing network), but public resistance would be massive. Much economic dislocation would result since, for example, over 25% of retail sales are travel-related. The energy savings would be modest since only 25% of the nation's energy is consumed by transportation. However, all pollution would be reduced substantially since transportation accounts for 75% of the carbon monoxide, 60% of the hydrocarbon, and 55% of the nitrogen oxide pollution in the nation. Problems related to the implementation of large-scale substitution are discussed.

    1975-01-01

    An evaluation is conducted of the current telecommunication link design technique and a description is presented of an alternative method, called the probability distribution method (PDM), which is free of the disadvantages of the current technique while retaining its advantages. The PDM preserves the simplicity of the design control table (DCT) format. The use of the DCT as a management design control tool is continued. The telecommunication link margin probability density function used presents the probability of achieving any particular value of link performance. It is, therefore, possible to assess the performance risk and other tradeoffs.

  17. Key Elements of Strategy in the Telecommunication Industry – Overview of Discussion

    Directory of Open Access Journals (Sweden)

    Ladislav Možný

    2017-10-01

    Full Text Available The purpose of this article is to examine current empirical and theoretical approaches to the strategies of companies operating in the telecommunication industry and to identify important strategy elements for the telecommunication industry. These elements are systematically categorized into the overall strategic framework. Strategic elements not covered in current literature are identified as topics for future research. As the first conclusion, the article identifies the most frequent strategic element discussed in connection with the strategy in the telecommunication industry which is Market offering/Value proposition including its more detailed structure. Highly debated elements of Market offering are Price and Product and their features. On the other hand, only limited attention is paid to Resources and no attention at all is paid to Value chain in the selected articles. Thus, there is space for future research regarding strategy in telecommunications mainly in the areas of Value chain and Resources (both tangible and intangible. Even Market offering is highly debated, the strategic element Availability (sales and service channels from the Market offering/Value proposition is covered only marginally and thus it should be a subject for future research.

    Patricelli, Frédéric; Beakley, James E; Carnevale, Angelo; Tarabochia, Marcello; von Lubitz, Dag K J E

    2009-03-01

    Among the most typical consequences of disasters is the near or complete collapse of terrestrial telecommunications infrastructures (especially the distribution network--the 'last mile') and their concomitant unavailability to the rescuers and the higher echelons of mitigation teams. Even when such damage does not take place, the communications overload/congestion resulting from significantly elevated traffic generated by affected residents can be highly disturbing. The paper proposes innovative remedies to the telecommunications difficulties in disaster struck regions. The offered solutions are network-centric operations-cap able, and can be employed in management of disasters of any magnitude (local to national or international). Their implementation provide ground rescue teams (such as law enforcement, firemen, healthcare personnel, civilian authorities) with tactical connectivity among themselves, and, through the Next Generation Network backbone, ensure the essential bidirectional free flow of information and distribution of Actionable Knowledge among ground units, command/control centres, and civilian and military agencies participating in the rescue effort.

  15. Advances in VRLA battery technology for telecommunications

    Energy Technology Data Exchange (ETDEWEB)

    Misra, Sudhan S. [SPM Consultants LLC, 112 Gwynmont Circle, North Wales, PA 19454 (United States)

    2007-05-25

    Wide scale use of the newly emergent VRLA (valve-regulated lead-acid) battery in telecommunication applications and the subsequent problems encountered early in their deployment history spurred intense efforts to improve the design as a continuous endeavor. After implementing improvements to battery placement and containment design to prevent the sudden onset of thermal runaway, the focus of the development work has been on cell internals. These include improved grid and strap alloys, superior AGM (absorbent glass mat) separator that retains compression in the cell, use of beneficial additives to the active materials and the need to avoid contaminants that promote detrimental side reactions. These improvements are now resulting in a vastly superior VRLA experience in the telecommunication applications. To further improve the reliability demanded by today's communication and internet environment VRLA battery installations should include continuous cell/module and system monitoring similar to that incorporated in competing advanced battery systems under development.

    Moorman, Bridget A; Cockle, Richard A

    2013-01-01

    Financial pressures, an aging population, and a rising number of patients with chronic diseases, have encouraged the use of remote monitoring technologies. This usually entails at least one physiological parameter measurement for a clinician. Mobile telecommunication technologies lend themselves to this functionality, and in some cases, avoid some of the issues encountered with device integration. Moreover, the inherent characteristics of the mobile telecommunications infrastructure allow a coupling of business and clinical functions that were not possible before. Table I compares and contrasts some key aspect of device integration in and out of a healthcare facility. An HTM professional may be part of the team that acquires and/or manages a system using a mobile telecommunications technology. It is important for HTM professionals to ensure the data is in a standard format so that the interfaces across this system don't become brittle and break easily if one part changes. Moreover, the security and safety considerations of the system and the data should be a primary consideration in and y purchase, with attention given to the proper environmental and encryption mechanisms. Clinical engineers and other HTM professionals are unique in that they understand the patient/clinician/device interface and the need to ensure its safety and effectiveness regardless of geographical environment.

  20. Use of satellite telecommunications for telemedicine

    Science.gov (United States)

    Tamkovich, Gennady

    1991-01-01

    The use of space telecommunications facilities in the interests of medicine should establish a reliable and timely connection between the specialists involved and access for each of them to information sources the need. Since a certain global-scale program should be implemented for this goal to be achieved, one of the top-priority tasks is to determine appropriate orbital facilities for telecommunications as well as appropriate areas and countries for them, outlining the territories where portable data receive/transport records can be placed and stations that are cheap and simple enough to operate can be stored. Eventually the satellite telecommunications system should encourage health workers to unite in a world community on the basis of a regular and efficient information exchange with the goal of protecting the health of man and the peace of Earth. This goal could only be achieved by gradually removing differences in the domain of medical education and information in different regions over the globe, by providing a possibility of rapid and coordinated access to the information on medical problems of interest on the global scale, as well as by coordinating the discussion and solution of all problems associated with the development and progress of the satellite communications system.

  1. Laminated wood as an alternative to wood poles : Engineered wood structures for electric utility and telecommunications industries

    Energy Technology Data Exchange (ETDEWEB)

    Reisdorff, R. [Laminated Wood Systems Inc., Seward, NE (United States)

    2002-07-01

    In this PowerPoint presentation, the author discusses the major advantages of laminated structures, for both the electric and telecommunication industries. The advantages include economy, quick delivery, climbing and field modifications, dimensional uniformity and stability. A series of pictures was displayed which showed the manufacturing process. Laminated structures have a proven history. They were developed in Europe in 1890, and introduced to the United States in 1934. Framing members were introduced in the late 1940s, while poles were introduced in 1963, two years ahead of steel poles. Some of the electrical utility applications include: (1) distribution structures, (2) transmission structures such as single-pole, phase over phase switch structures, tangent structures, and H-Frame construction. The applications for the telecommunication industry consist of joint use structures, such as electric and telecommunication, lighting and telecommunication, overhead telephone and wireless; mono-pole applications; three-pole Bell Towers; and tree poles. Examples of each type were shown. figs.

  2. The evolution of investments decision mode in China's telecommunication

    ZHANG Ai-hua; ZHAO Lian-qiang; SHU Hua-ying

    2007-01-01

    This essay analyzes the data of Chinese telecommunication market, telecommunication investments and investment benefits over the past 20 years. On the basis of these data, the essay reviews Chinese changing telecommunication policies and discusses the major events in the course of China's telecommunication development. It is argued that telecommunication policies, regime backgrounds and market demand characteristics have a significant impact on investment decision mode in telecommunication industry. The evolution of network investments decision mode in China's telecommunication has corresponded to the transformation of these key factors. Considering the special events in the development of Chinese telecommunication as divisions, the essay discusses three stages of the evolution of investments decision mode in China's telecommunication. With the firm environment and problems that Chinese telecommunication operators have been facing since 2000 analyzed. it is demonstrated that Chinese telecommunication operators should change their mode of investment decision into the "profit-oriented investment decision mode" in order to achieve a high growth performance in the capital market,. This investment decision mode will result in increase of the investment profit with limited investment capital. The main procedure of profit-oriented investment decision mode is set out, which is abstracted to a mathematical model eventually.

  3. Advertising and Consumer Choice of Telecommunication Services in Nigeria

    Directory of Open Access Journals (Sweden)

    David Oladipo Olalekan

    2015-09-01

    Full Text Available This study examines the critical influence of advertising on consumer choice of telecommunication services in Nigeria. The advertisement played a key role in providing the consumers with product information. The study investigates the effect of marketing medium of telecommunication as a proxy for advertisement on preference of telecommunication services as a proxy for consumer choice in Nigeria. The Binary Logit Model (BLM and descriptive analytical frameworks are used to evaluate the statistical importance of advertisement, quality of services, income of the consumer, product’s self and related service charges for a consumer choice of telecommunication services through Wald test. The findings show that product’s self service charge and service quality are statistically significant for a consumer choice of telecommunication services in Nigeria at 1 percent significance level. And, related product’s service is statistically significant for a consumer choice of telecommunication services in Nigeria at 5 percent significance level. While advertisement and income of the consumer are statistically significant for a consumer choice of telecommunication services in Nigeria at 10 percent. The study concludes that advertisement is important for the choice of telecommunication services in Nigeria but having less impact. And, product’s self service charge and service quality are hugely significant for the choice of telecommunication services in Nigeria. Therefore, the sector of telecommunications needs more investment in advertisement so as to have telecommunications’ products information spread in order to stimulate the increase in demand for telecommunication services in Nigeria.

  4. Laying the Groundwork: Lessons Learned from the Telecommunications Industry for Distributed Generation; Preprint

    Energy Technology Data Exchange (ETDEWEB)

    Wise, A. L.

    2008-05-01

    The telecommunications industry went through growing pains in the past that hold some interesting lessons for the growing distributed generation (DG) industry. The technology shifts and stakeholders involved with the historic market transformation of the telecommunications sector mirror similar factors involved in distributed generation today. An examination of these factors may inform best practices when approaching the conduits necessary to accelerate the shifting of our nation's energy system to cleaner forms of generation and use. From a technical perspective, the telecom industry in the 1990s saw a shift from highly centralized systems that had no capacity for adaptation to highly adaptive, distributed network systems. From a management perspective, the industry shifted from small, private-company structures to big, capital-intensive corporations. This presentation will explore potential correlation and outline the lessons that we can take away from this comparison.

    2015-09-01

    Full Text Available The telecommunications sector is going through an interesting phase in its evolution. Cellular mobile service providers have been at the root of the massive expansion in the number of subscribers and usage. Since last year the pace of growth has slowed down and it is increasingly clear that revenues from voice services alone will not be sufficient. The action has now moved to data. In fact, mobile service providers have seen a rapid increase in their revenues from data. Data, however, is more complex than voice. The key challenges are explored here.

    EUTELSAT II is a regional public telecommunications system for Europe. The services which will be provided are telephone and television. The satellites will be placed at a geostationary orbit within the arcs of 6 degrees east to 19 degrees east or 26 degrees to 36 degrees east. The designed lifetime is 7 years. After separation of the satellites from the launch vehicles, telemetry, telecommand, and ranging will be performed within the S-band frequencies. After positioning of the satellite at its final geostationary orbit, the Ku-band telecommunication equipment will be activated. From this time on, all satellite control operations will be performed in Ku-band. The Deep Space Network (DSN) will support the transfer and drift orbit mission phases. The coverage will consist of the 26-m antennas at Goldstone and Canberra as prime support for the transfer and drift orbits. Maximum support will consist of a 7-day period, plus 14 days of contingency support. Information is given in tabular form for DSN support, frequency assignments, telemetry, command, and tracking support responsibility.

  1. Fire protection for telecommunications central offices

    International Nuclear Information System (INIS)

    McKenna, L.A. Jr.

    1990-01-01

    The provision of continuous, uninterrupted telecommunications service is vital to modern life. In order to provide uninterrupted service to customers, a service continuity program has been in place with AT and T for many years. This program integrates many different protection strategies and plans, each designed to mitigate one of the many threats to service continuity. The fire protection program implemented within AT and T is a part of this service continuity program. In the design of this program, a number of unusual problems had to be addressed due to the service continuity requirements. Typical solutions to fire protection problems (ignition prevention, detection, and suppression) which are embodied in building and fire prevention codes are inadequate to provide service continuity. This presentation outlines the basic arrangement of a telecommunications central office, the specific fire protection problems encountered, the fire protection philosophy developed through the use of a systems approach, and the implementation of the fire protection program. Special emphasis is placed on the strategies employed in lieu of more traditional fire protection schemes and the stimuli for selecting them

    ENGLISH ABSTRACT: With the embracing of neV'( management philosophies or redesigned processes, it is becoming a popular opinion that often the practical problem lies with the implementation of the new concept, rather than with the concept itself. By focussing on certain generic critical actions, chances of successful implementation increases for any new philosophy or re-engineered process. This article discusses such critical success actions, or implementation drivers as experience in a BPR project at Siemens Telecommunications.

    AFRIKAANSE OPSOMMING: 'n Gewilde siening ten opsigte van die bekendstelling van nuwe bestuursfilosofiee, of implementering van herontwerpde prosesse, is dat die probleem gewoonlik Ie by die implementering daarvan, eerder as by die beginsels van die bestuursfilosofie wat geimplementeer word . Deur op generies kritieke faktore te konsentreer, kan die kanse op suksesvolle implementering van bykans enige bestuursfilosofie of herontwerpde proses verbeter word. Hierdie artikel bespreek sulke kritieke sukses aksies, of implementeringsdrywers, aan die hand van 'n gevallestudie soos ervaar in 'n BPR projek by Siemens Telecommunications.

    2015-12-01

    Full Text Available European countries have gone through serious efforts to overcome the financial crisis and special measures had to be taken in order to limit the negative impact on businesses and stabilize a healthy economic environment for the single market. The specific governmental policies aimed to keep under control the effects of the crisis and relaunch the economic growth, but they were unpopular among a part of the European citizens. The economic situation forced most managers of private companies to rethink the business strategy and restructure the activity. Lately, Greece has been going through a difficult period, as the crisis worsened the economic situation of the country. The population did not welcome the drastic economic measures which were proposed by IMF and institutional creditors and this conflict almost lead to national insolvency. The problems of Greece are deeply rooted in the business models and economic philosophy. This paper has the purpose of analyzing the corporate governance regulation and practices in Greece and to determine whether it is possible to enhance business profitability and stability by enforcing a better legal framework in the area of corporate governance. The research focuses on the calculation of a corporate governance index for a selection of Greek companies form different sectors of activity (oil &gas, telecommunications, beverages and the analysis of the results may lead to the identification of weaknesses in this domain. Improvements in the corporate governance practices are considered to lead to enhancing business stability and sustainability. The methodology for calculating the corporate governance index is adapted for Greek companies and is in accordance with the provisions of the Hellenic Corporate Governance Code.

    Full Text Available Through outsourcing, a company can expand and develop its sources and capacities by accessing to higher quality services and better functionality. This paper deals with the perception of the managers of the telecommunication industry sector on the effects of outsourcing on operational strategy and especially on the issues associated with cost reduction, developed quality, flexibility and better service. Because of the importance of the strategic feature of outsourcing, we examined its effects on the organizational function of the telecommunication industries. This study shows that managers believe that outsourcing has a great impact not only on the cost reduction but also on other goals of operational strategies, which makes outsourcing become inherently more strategic. In addition, it seems that outsourcing influences function noticeably. In the present research, the relationships between propensity to outsourcing and operational objectives and organizational performance in telecommunication industries are assessed. The aim of this research is to examine the propensity to outsourcing and its impacts on operational objectives including cost reduction, improved quality, flexibility and better service and organizational performance, which includes financial performance and non-financial performance. In the research, data are collected through field research and questionnaires. The questionnaires are distributed among the board of directors, quality managers, operational administrators, and lower managers and then the feedbacks are analyzed using SPSS and Minitab software based on deductive and descriptive statistics.

    Near-miss event reporting systems have a successful history in managing risk in industries such as medicine, aviation, nuclear power, and the petrochemical industry. By treating events of customer dissatisfaction as accidents, near-miss event reporting systems designed to reduce risks to safety in hazardous environments may be borrowed by the telecommunications industry. The system chosen for this study was the Prevention and Recovery Information System for Monitoring and Analysis (PRISMA), developed by the Eindhoven University of Technology (EUT). The purpose of this study was to determine the feasibility of applying PRISMA as a tool to reduce risks to customer dissatisfaction. Participants in the project included the EUT Safety Management Group, a consultant, and six Network Service Managers from a telecommunications company whose duties included responding to customer complaints. Twenty-three incidents were investigated with an average of 5.9 root causes arising from 2.9 process owners per event. Causal trees were generated for each incident and root causes were classified according to the Eindhoven Classification Model (ECM). The distribution of 135 root causes was 50% organizational, 32% human, 16% technical and 2% unclassifiable. The participants were successful in executing the functional steps of PRISMA in response to incidents of customer dissatisfaction. This study established the suitability of PRISMA as a tool for managing risks to customer satisfaction within the telecommunications domain

    2013-01-01

    Radios today are evolving from awareness toward cognition. A software defined radio (SDR) provides the most capability for integrating autonomic decision making ability and allows the incremental evolution toward a cognitive radio. This cognitive radio technology will impact NASA space communications in areas such as spectrum utilization, interoperability, network operations, and radio resource management over a wide range of operating conditions. NASAs cognitive radio will build upon the infrastructure being developed by Space Telecommunication Radio System (STRS) SDR technology. This paper explores the feasibility of inserting cognitive capabilities in the NASA STRS architecture and the interfaces between the cognitive engine and the STRS radio. The STRS architecture defines methods that can inform the cognitive engine about the radio environment so that the cognitive engine can learn autonomously from experience, and take appropriate actions to adapt the radio operating characteristics and optimize performance.

    1994-01-01

    The purpose of this paper is twofold: to discuss high temperature superconductors with specific reference to their employment in telecommunications applications; and to discuss a few of the limitations of the normally employed two-fluid model. While the debate on the actual usage of high temperature superconductors in the design of electronic and telecommunications devices-obvious advantages versus practical difficulties-needs to be settled in the near future, it is of great interest to investigate the parameters and the assumptions that will be employed in such designs. This paper deals with the issue of providing the microwave design engineer with performance data for such superconducting waveguides. The values of conductivity and surface resistance, which are the primary determining factors of a waveguide performance, are computed based on the two-fluid model. A comparison between two models-a theoretical one in terms of microscopic parameters (termed Model A) and an experimental fit in terms of macroscopic parameters (termed Model B)-shows the limitations and the resulting ambiguities of the two-fluid model at high frequencies and at temperatures close to the transition temperature. The validity of the two-fluid model is then discussed. Our preliminary results show that the electrical transport description in the normal and superconducting phases as they are formulated in the two-fluid model needs to be modified to incorporate the new and special features of high temperature superconductors. Parameters describing the waveguide performance-conductivity, surface resistance and attenuation constant-will be computed. Potential applications in communications networks and large scale integrated circuits will be discussed. Some of the ongoing work will be reported. In particular, a brief proposal is made to investigate of the effects of electromagnetic interference and the concomitant notion of electromagnetic compatibility (EMI/EMC) of high T c superconductors

    Chandler, Charles W.; Miranda, Felix A. (Technical Monitor)

    2004-01-01

    Each future mission to Jupiter and beyond must carry the traditional suite of telecommunications systems for command and control and for mission data transmission to earth. The telecommunications hardware includes the large antenna and the high-power transmitters that enable the communications link. Yet future spacecraft will be scaled down from the hallmark missions of Galileo and Cassini to Jupiter and Saturn, respectively. This implies that a higher percentage of the spacecraft weight and power must be dedicated to telecommunications system. The following analysis quantifies this impact to future missions and then explores the merits of an alternative approach using deep space relay stations for the link back to earth. It will be demonstrated that a telecommunications relay satellite would reduce S/C telecommunications weight and power sufficiently to add one to two more instruments.

  12. Nanoscale resonant-cavity-enhanced germanium photodetectors with lithographically defined spectral response for improved performance at telecommunications wavelengths.

    Science.gov (United States)

    Balram, Krishna C; Audet, Ross M; Miller, David A B

    2013-04-22

    We demonstrate the use of a subwavelength planar metal-dielectric resonant cavity to enhance the absorption of germanium photodetectors at wavelengths beyond the material's direct absorption edge, enabling high responsivity across the entire telecommunications C and L bands. The resonant wavelength of the detectors can be tuned linearly by varying the width of the Ge fin, allowing multiple detectors, each resonant at a different wavelength, to be fabricated in a single-step process. This approach is promising for the development of CMOS-compatible devices suitable for integrated, high-speed, and energy-efficient photodetection at telecommunications wavelengths.

  13. Standby battery requirements for telecommunications power

    Energy Technology Data Exchange (ETDEWEB)

    May, G.J. [The Focus Partnership, 126 Main Street, Swithland, Loughborough, Leics LE12 8TJ (United Kingdom)

    2006-08-25

    The requirements for standby power for telecommunications are changing as the network moves from conventional systems to Internet Protocol (IP) telephony. These new systems require higher power levels closer to the user but the level of availability and reliability cannot be compromised if the network is to provide service in the event of a failure of the public utility. Many parts of these new networks are ac rather than dc powered with UPS systems for back-up power. These generally have lower levels of reliability than dc systems and the network needs to be designed such that overall reliability is not reduced through appropriate levels of redundancy. Mobile networks have different power requirements. Where there is a high density of nodes, continuity of service can be reasonably assured with short autonomy times. Furthermore, there is generally no requirement that these networks are the provider of last resort and therefore, specifications for continuity of power are directed towards revenue protection and overall reliability targets. As a result of these changes, battery requirements for reserve power are evolving. Shorter autonomy times are specified for parts of the network although a large part will continue to need support for hours rather minutes. Operational temperatures are increasing and battery solutions that provide longer life in extreme conditions are becoming important. Different battery technologies will be discussed in the context of these requirements. Conventional large flooded lead/acid cells both with pasted and tubular plates are used in larger central office applications but the majority of requirements are met with valve-regulated lead/acid (VRLA) batteries. The different types of VRLA battery will be described and their suitability for various applications outlined. New developments in battery construction and battery materials have improved both performance and reliability in recent years. Alternative technologies are also being proposed

  15. Telecommunications, politics, economics, and national sovereignty: A new game

    1996-12-31

    The impact of telecommunications on politics, economics and national sovereignty is creating a new game. Political and economic power may operate over the same territory, as in the now-rare case of isolated economies, but, more often, their domains do not coincide. Increasingly, telecommunications create major challenges for countries preoccupied with issues of national sovereignty because the national state has only a limited ability to control these intrinsic and at times potentially destabilizing powers of telecommunications and the {open_quotes}telecommunities{close_quotes} they make possible. As many traditional aspects of sovereignty are becoming weakened by telecommunications, and as the intense dynamics of networks and the expansion of telecommunities revolutionize business and politics, there is a need to prevent the situation from becoming chaotic and uncontrollable, even while recognizing the possibilities of enhanced opportunities. This requires focusing on a more flexible conception of sovereignty which can enhance the state`s attractiveness for telecommunications infrastructure, while addressing issues of ethics and morality in the new telecommications environment. A new, broad socio-technological research agenda needs to be developed - with the ultimate purpose of providing society with the tools to play the new game and thrive. 10 refs., 3 tabs.

  17. Space Telecommunications Radio System (STRS) Compliance Testing

    Science.gov (United States)

    Handler, Louis M.

    2011-01-01

    The Space Telecommunications Radio System (STRS) defines an open architecture for software defined radios. This document describes the testing methodology to aid in determining the degree of compliance to the STRS architecture. Non-compliances are reported to the software and hardware developers as well as the NASA project manager so that any non-compliances may be fixed or waivers issued. Since the software developers may be divided into those that provide the operating environment including the operating system and STRS infrastructure (OE) and those that supply the waveform applications, the tests are divided accordingly. The static tests are also divided by the availability of an automated tool that determines whether the source code and configuration files contain the appropriate items. Thus, there are six separate step-by-step test procedures described as well as the corresponding requirements that they test. The six types of STRS compliance tests are: STRS application automated testing, STRS infrastructure automated testing, STRS infrastructure testing by compiling WFCCN with the infrastructure, STRS configuration file testing, STRS application manual code testing, and STRS infrastructure manual code testing. Examples of the input and output of the scripts are shown in the appendices as well as more specific information about what to configure and test in WFCCN for non-compliance. In addition, each STRS requirement is listed and the type of testing briefly described. Attached is also a set of guidelines on what to look for in addition to the requirements to aid in the document review process.

    A flight-qualified implementation of a Software Defined Radio (SDR) Operating Environment for the JPL-SDR built for the CoNNeCT Project has been developed. It is compliant with the NASA Space Telecommunications Radio System (STRS) Architecture Standard, and provides the software infrastructure for STRS compliant waveform applications. This software provides a standards-compliant abstracted view of the JPL-SDR hardware platform. It uses industry standard POSIX interfaces for most functions, as well as exposing the STRS API (Application Programming In terface) required by the standard. This software includes a standardized interface for IP components instantiated within a Xilinx FPGA (Field Programmable Gate Array). The software provides a standardized abstracted interface to platform resources such as data converters, file system, etc., which can be used by STRS standards conformant waveform applications. It provides a generic SDR operating environment with a much smaller resource footprint than similar products such as SCA (Software Communications Architecture) compliant implementations, or the DoD Joint Tactical Radio Systems (JTRS).

    As mines utilize more automation in mining operations to improve efficiency and safety, a corresponding increasing demand is placed on the transport of information. Some of the recent technological advances in underground telecommunications are described for various data, voice and video applications. In particular, two new innovative underground communication systems are described, one with highspeed data at 30 Mbps and the other for mine-wide evacuation and safety applications. The high-speed data system incorporates state-of-the-art data networking technologies and the existing leaky-cable, narrow-band radio channels. The new system provides over the same basic infrastructure - the highspeed data network at 30 Mbps TCP/IP Ethernet with 100 Base-T interconnection, plus 32 narrow-band radio channels. The second system is a system for mine-wide evacuation with 'through-the-earth' communication infrastructure. Emergency situations can be communicated to and from all the miners within seconds through a central control location. The technology involved does not require leaky cable or any other similar transmission media installation. Many applications are possible, including warning miners of emergency situations, mine rescue operation to communicate with trapped miners, and regular reporting from miners working alone.

    2016-07-01

    Full Text Available With rapid cultural, demographical and economic changes in knowledge oriented economy, employee creativity has become a challenge for organizations, as this works as a core competence. We suggest that leaders with ethical commitment help to nourish creativity in employees. Using social learning theory, authors examined the influence of ethical leadership on employee creativity through the mediation of self-efficacy. This study also explored the moderating role of uncertainty avoidance between the relationship of ethical leadership and employee creativity. Data was collected from 180 employees along with their supervisors from four different telecommunication companies working in Pakistan. The questionnaire was adopted and tested on the criteria of five point Likert scale. Regression and Correlation tests were used to check hypothesis. Supervisors of these four companies evaluated the creativity of the selected staff member groups while the employees and staff members reported the perceptions about their supervisors in terms of ethical leadership. Results showed that ethical leadership was positively related to employee creativity and this relationship was mediated by self-efficacy and this mediation was partial. There was significant negative relationship between uncertainty avoidance and employee creativity, this is the main aspect of present study. According to the results uncertainty is negatively associated with the employee creativity it means high uncertainty results in low creativity of employees. This study was conducted in Pakistani context where uncertain attitude is very common in society so uncertainty avoidance affects creativity of the employee in Pakistani organizations. Our study offer practical implications for telecommunication companies in order to achieve competitive advantage by enhancing employee creativity, as employee creativity makes organization creative.

    2011-01-01

    This study was to determine the prevalence and work-related risk factors of neck-upper extremity musculoskeletal disorders (MSDs) among video display terminal (VDT) users. A comparative cross-sectional study was conducted; there were 60 VDT users and 35 controls. The participants filled in a structured questionnaire, had electrophysiological tests and an X-ray of the neck. The prevalence of MSDs was higher (28.3%) among VDTs users compared to controls (14.3%) with no statistically significant difference. The prevalence of cervical disorders with or without radiculopathy (18.3%) was the most common disorder followed by carpal tunnel syndrome (6.6%). The mean (SD) age of MSD cases (51 ± 7.2 years) was statistically significantly higher than of the controls (42.8 ± 9). Physical exposure to prolonged static posture (OR: 6.9; 95% CI: 0.83-57.9), awkward posture (OR: 5.5; 95% CI: 0.6-46.4) and repetitive movements (OR: 5.5; 95% CI: 0.65-46.4) increased risk of MSDs with a statistically significant difference for static posture only (p < .05). VDT users experienced more job dissatisfaction, work-overload and limited social support from supervisors and colleagues. VDT use did not increase the risk of neck-upper extremity MSDs. The risk increased with older age and static posture.

    2002-05-01

    This project was designed as a social science complement to the engineering studies supported by the University of Rhode Island (URI) Transportation Center (URITC). The project developed a behavioral knowledge base about the actual and intended transport and telecommunications behaviors of transportation users, with a particular focus on southern Rhode Island. Background studies, drawing from literature on telecommuting and travel behavior, led to the development of a generalized framework to understand the transport-telecom interactions. In particular, we developed working papers dealing with transport aspects of e-retailing and distance education. In the empirical part of this project, two major field studies were completed. The first of these was a survey of URI students, probing their car travel, carpool, bus use, and Internet use behaviors. The students were surveyed first by telephone, selected randomly from a list obtained from the Register's office. A total of 220 students responded to the telephone survey. Characteristics of the telephone survey respondents are shown in Appendix B. This was supplemented by an in-class survey of 107 students conveniently selected from the courses taught by the research faculty. This supplementary questionnaire probed the students more deeply regarding their motivations for transportation and technology use issues. The second major field study was a mail survey of southern Rhode Island residents. In this survey, we not only investigated actual travel and transport behaviors but also measured attitudes towards the environment and alternative transport and telecommuting solutions. At the time of writing this report, about 850 individuals had responded to our mail questionnaire. Characteristics of the resident sample are described in Appendix B. The results have laid the groundwork for our second year project where we plan to study the impact of specific interventions on transportation and telecommuting attitudes and intentions.

    2013-08-01

    Full Text Available Customer relationship management (CRM plays an important role on marketing planning. In this paper, we re-examine the effect of having efficient CRM on efficiency of a telecommunication company. The proposed study considers three hypotheses. The first hypothesis examines whether implementation of CRM could improve customer’s perception in terms of customer retention, satisfaction, loyalty and awareness. The second hypothesis examines whether implementation of CRM influences on market performance in terms of reduction on customer complaints, quality improvement, improving customer perception, access to services and increase in market share. Finally, the third hypothesis considers the effect of CRM on financial figures in terms of sales growth, profit growth, earnings per share and productivity. The results of our survey have confirmed the first hypothesis and rejected the third hypothesis. In other words, while CRM improves customer perception it does not influence financial figures in most cases (P<0.01.

  13. Regulation of Telecommunications: The Choice Between Market and Regulatory Failures

    Directory of Open Access Journals (Sweden)

    Dmitrii Trubnikov

    2017-04-01

    Full Text Available Purpose – The paper examines the main regulatory frameworks of the telecommunications industry through the concept of market failure and analyses how and why the policy often leads to undesirable outcomes that might be considered as regulatory failure. Methodology/approach/design – The research uses the EU regulatory framework for electronic communications as a base for the analysis of the main policy objectives through the prism of the market failure theory with an eye to the interests of the main market players in the telecommunications markets. Findings – About any aspect of regulation allows to find ways to create opportunities for some groups of the industry and stifle activity of others. Despite the theory of market failure provides reasonable justifications for regulation of telecommunications markets, it is possible to argue that many of these problems are mainly the consequence of the policy and could be better solved by market mechanisms. Originality/value – The results of the research allow to look at the problems of telecommunications development and issues of the high level of concentration of the telecommunications markets as regulatory formed problems rather than consequences of the inherited industry’s characteristics.

    Fouladvand, M. Ebrahim; Darooneh, Amir H.

    We present an analytical study of an insurance company. We model the company's performance on a statistical basis and evaluate the predicted annual income of the company in terms of insurance parameters namely the premium, the total number of insured, average loss claims etc. We restrict ourselves to a single insurance class the so-called automobile insurance. We show the existence of a crossover premium pc below which the company is operating at a loss. Above pc, we also give a detailed statistical analysis of the company's financial status and obtain the predicted profit along with the corresponding risk as well as ruin probability in terms of premium. Furthermore we obtain the optimal premium popt which maximizes the company's profit.

    2014-10-01

    Full Text Available The scientific and professional research on technological and telecommunication development started in the second half of the 20th century as the use of new media and technologies began to cause structural business and social changes. A review of research published in the early 1980s revealed that the focus was mainly on the acceptance, usefulness and impact of new media and information technology on the information society, whereas research conducted at the turn of the century was mostly interdisciplinary and related to the effect of technological and telecommunication development on various scientific and professional fields. The focus of this paper is an overview of published research on information technology since the 1980s to date, as well as technological and telecommunication development in recent years based on the latest official published data. On the basis of previous research, it can be concluded that more attention needs to be directed to monitoring trends of ICT products and services in order to increase benefits and reduce the costs for active users, as well as improving infrastructure and providing information to attract passive users in order to reduce technological and telecommunication gap between developed, developing and underdeveloped countries.

    Full Text Available Companies, especially nowadays, are characterized through great mobility, fast circulation of capital, occurring in their chase for profit. In this context, companies look for alliances, economical and political assistance. These objectives can materialize through merging of companies. The merger can be internal (between Romanian companies or transboundary, which includes foreign companies. In order to correctly reflect these events, the merger operations must be regulated and must respect national and international regulations. One important request concerning the merger operations is that the accounting values of the assets, debts and ownership equity must be brought to the present financial value.

    Fleetwood, Daniel M.; Winokur, Peter S.

    1999-01-01

    Trapped protons and electrons in the Earth's radiation belts and cosmic rays present significant challenges for electronics that must operate reliably in the natural space environment. Single event effects (SEE) can lead to sudden device or system failure, and total dose effects can reduce the lifetime of a telecommmiications system with significant space assets. One of the greatest sources of uncertainty in developing radiation requirements for a space system is accounting for the small but finite probability that the system will be exposed to a massive solar particle event. Once specifications are decided, standard laboratory tests are available to predict the total dose response of MOS and bipolar components in space, but SEE testing of components can be more challenging. Prospects are discussed for device modeling and for the use of standard commercial electronics in space

    Jussawalla, M; Ogden, M R

    1989-03-01

    The Independent Commission for World-Wide Telecommunications Development (Maitland Commission) reported that telecommunication networks, including public telephone systems, are an infrastructure which aids economic development throughout the world. The Commissions objective is to bring the majority of the world's population within easy access of a telephone and, in time, other communications services. Development in the Pacific Islands region is slowed by a lack of efficient communications. The islands are spread over 29 million square kilometers of ocean and extremely vulnerable to natural disasters. Pacific Island Nations (PINs) have problems of foreign exchange, skill shortages, and poor credit terms. Telecommunications infrastructure audits showed the overall regional teledensity of 3 telephones per 100 population. The individual countries vary form 8.3 in Fiji to 1.5 in Papua New Guinea and 25.2 in New Zealand. The population of the developing island countries is in mostly rural areas where there is a chronic shortage of telephones. The constraints on radio systems can be overcome with satellite technology. The new technologies are coming on the market faster than these countries can afford to handle them. By using satellite technology and sharing facilities PINs can greatly reduce the cost of telecommunications systems. Fiber optic cables will be used to carry large volumes of traffic over major routes while satellites can be used for a array of services for the smallest PIN nation to the largest route rim country. Work is being done to standardize the equipment specifications and to develop policies for the coordination of regional telecommunications training. To further facilitate communications development in this area, changes need to be made in international funding priorities for development, and recommendations by the Maitland Commission must be taken seriously.

    Directory of Open Access Journals (Sweden)

    Mirjana Pejić Bach

    2013-01-01

    Full Text Available Telecommunication markets are a valuable factor that contributes to the economic growth and development. The development of the telecommunication markets and services was slower in the countries in transition than in developed European countries, altough after the fall of communism countries in transition implemented a big progress in spreading and modernizing of their telecommunication network.The paper analysis the level of concentration of telecommunication industry in Croatia from 2003 to 2008. The data used in the analysis consider 50 Croatian largest IT firms that are operating on telecommunication market and specific telecommunication sectors: producers of telecommunication equipment, distributers of telecommunication services and implementers of telecommunication solutions. The main two conclusions of this article are: (1 degree of concentration on the telecommunication market in Croatia changed differently in different market shares, (2 degree of concentration on the telecommunication market in Croatia is influenced by different barriers to enter the market.The analysis finds that Croatian telecommunication industry is in a good position even a few steps ahead of some other transition countries.

  14. Competitive intelligence information management and innovation in small technology-based companies

    Science.gov (United States)

    Tanev, Stoyan

    2007-05-01

    In this article we examine how (i) company type and (ii) the competitive intelligence information used by small technology-based companies affect their innovation performance. The focus is on the specific information types used and not on the information sources. Information topics are classified in four groups - customers (10), company (9), competitor (11) and industry (12). The sample consists of 45 small new technology-based companies, specialized suppliers, and service companies from a variety of sectors - software, photonics, telecommunications, biomedical engineering and biotech, traditional manufacturing etc. The results suggest that the total number of intelligence information topics companies use to make decisions about innovation is not associated with the number of their new products, processes, services and patents. Therefore the companies in our sample do not seem to have the resources, processes or value systems required to use different competitive intelligence information when making decisions on innovation or may rely more on their own internal logic than on external information. Companies are classified using a Pavitt-like taxonomy. Service companies are considered as a separate company type. This allows for explicitly studying both, the innovative role of new services in product driven companies, and the role of new product development in service companies.

  17. [Scientific role of German ophthalmology in the European telecommunication project OPHTEL].

    Science.gov (United States)

    Mertz, M; Mann, G; Zahlmann, G; Obermaier, M

    1997-07-01

    In Denmark, France, Germany, Great Britain and Italy, the OPHTEL project combines clinical centers of ophthalmology and internal medicine, an institute for medical informatics and health services research, a publishing company and different industrial partners in the EDP market. With the aid of visual telecommunication and rapid data transfer, methods and conditions will be developed and proved so that any physician can very easily obtain sufficient information for treating his patient. Thus, the regional differences in the quality of structured health service (e.g., urban/ rural) will be overcome throughout Europe. SCIENTIFIC TASKS: A multilingual diagnostic and therapeutic thesaurus has to be worked out in order to create standards for communication and quality control. Based on literature, images and image analysis in a knowledge-based data bank, a monitoring system (containing watch-dog functions) and the basic aspects of an ophthalmological patient/disease register will be investigated. (In parallel, a technical development of synchronous and asynchronous telecommunication between eye physicians is taking place in close cooperation with the regional Bavarian project Teleopathalmology in Bavaria on-line). State of the art 6 months after starting the project:the knowledge-based image data bank has been founded and also an ophthalmological 8 language thesaurus and definition standard. All data transfer lines are installed. The project is taking place amid diverging sections of medicine: ophthalmology and internal medicine, health politics and data protection, individual treatment and common interest (health care), product management and office organization. Thus, the scientific quality of the transferred ophthalmological content must undergo sophisticated controls. FUTURE STEPS: Intense cooperation with the big German associations for ophthalmology (DOG, BVA) and the European ophthalmological societies concerning EDP, classification and quality control.

    Kantar, E.; Deviren, B.; Keskin, M.

    2011-11-01

    We present a study, within the scope of econophysics, of the hierarchical structure of 98 among the largest international companies including 18 among the largest Turkish companies, namely Banks, Automobile, Software-hardware, Telecommunication Services, Energy and the Oil-Gas sectors, viewed as a network of interacting companies. We analyze the daily time series data of the Boerse-Frankfurt and Istanbul Stock Exchange. We examine the topological properties among the companies over the period 2006-2010 by using the concept of hierarchical structure methods (the minimal spanning tree (MST) and the hierarchical tree (HT)). The period is divided into three subperiods, namely 2006-2007, 2008 which was the year of global economic crisis, and 2009-2010, in order to test various time-windows and observe temporal evolution. We carry out bootstrap analyses to associate the value of statistical reliability to the links of the MSTs and HTs. We also use average linkage clustering analysis (ALCA) in order to better observe the cluster structure. From these studies, we find that the interactions among the Banks/Energy sectors and the other sectors were reduced after the global economic crisis; hence the effects of the Banks and Energy sectors on the correlations of all companies were decreased. Telecommunication Services were also greatly affected by the crisis. We also observed that the Automobile and Banks sectors, including Turkish companies as well as some companies from the USA, Japan and Germany were strongly correlated with each other in all periods.

    Lilly, Michelle M; London, Melissa J; Mercer, Mary C

    2016-03-01

    This study aims to: (1) examine rates of obesity and physical health complaints among 911 telecommunicators; and (2) document the role of emotion dysregulation, psychological inflexibility, duty-related distress and dissociation, and psychopathology in predicting obesity and physical health complaints in this population. The sample consisted of 911 telecommunicators from across the country (N = 758). Participants completed an online survey assessing their mental and physical health functioning. A total of 82.5% of the sample reported a body mass index that fell within the overweight or obese category and an average of 17 physical health complaints within the past month. Peritraumatic reactions (distress and dissociation), emotion dysregulation, and psychological inflexibility had effects on physical health largely through psychopathology (alcohol abuse, post-traumatic stress disorder, and depression). Development of adapted prevention and intervention efforts with this population is needed.

  2. Approaches for a quantum memory at telecommunication wavelengths

    International Nuclear Information System (INIS)

    Lauritzen, Bjoern; Minar, Jiri; Riedmatten, Hugues de; Afzelius, Mikael; Gisin, Nicolas

    2011-01-01

    We report experimental storage and retrieval of weak coherent states of light at telecommunication wavelengths using erbium ions doped into a solid. We use two photon-echo-based quantum storage protocols. The first one is based on controlled reversible inhomogeneous broadening (CRIB). It allows the retrieval of the light on demand by controlling the collective atomic coherence with an external electric field, via the linear Stark effect. We study how atoms in the excited state affect the signal-to-noise ratio of the CRIB memory. Additionally we show how CRIB can be used to modify the temporal width of the retrieved light pulse. The second protocol is based on atomic frequency combs. Using this protocol we verify that the reversible mapping is phase preserving by performing an interference experiment with a local oscillator. These measurements are enabling steps toward solid-state quantum memories at telecommunication wavelengths. We also give an outlook on possible improvements.

  4. The protection of the Cyrillic alphabet in telecommunications: Taxation aspects

    Directory of Open Access Journals (Sweden)

    Marilović Đorđe

    2016-01-01

    Full Text Available The use of Cyrillic and other specific alphabets is discouraged in some telecommunication services. In this paper; the author focuses on unequal treatment of the Cyrillic alphabet in telecommunications (in SMS messages, which is incompatible with the interests of a multilingual society to cherish its linguistic heritage and diversity. Referring to the Convention on the Protection and Promotion of the Diversity of Cultural Expression (2005, the author suggests introducing measures which would lead to removing the discriminatory pricing of Cyrillic SMS messages; and introducing tax measures which would support mobile network operators and prevent possible market inequalities stemming from introducing these measures. The suggested solution is applicable to any multicultural society facing the same problem; regardless of languages in question.

    2014-04-01

    Full Text Available Paper presents telecommunications security issues with dynamically changing networking. Paper also presents performance indicators of authentication as an integral part of the approach to non-public information. Expected level of security depend on relevant ITS services requirements, different solutions require different levels of quality. Data volumes transferred both in private data vehicle on board networks as well as between vehicles and infrastructure or other vehicles significantly and progressively grow. This trend leads to increase of the fatal problems if security of the wide area networks is not relevantly treated. Relevant communications security treatment becomes crucial part of the ITS telecommunications solution because probability of hazards appearances grow if vehicles networks are integrated in the dynamically organized wide area networks. Besides of available "off shelf" security tools solution based on non-public universal identifier with dynamical extension and data selection according to actor role or category is presented including performances indicators for the authentication process.

    2013-01-01

    AMIGA is an extension of the Pierre Auger Observatory that will consist of 85 detector pairs, each one composed of a surface water-Cherenkov detector and a buried muon counter. Each muon counter has an area of 30 square meters and is made of scintillator strips, with doped optical fibers glued to them, which guide the light to 64 pixel photomultiplier tubes. The detector pairs are arranged at 433 m and 750 m array spacings. In this paper we present the telecommunications system designed to connect the muon counters with the central data processing system at the observatory campus in Malarg and quot;ue. The telecommunications system consists of a point-to-multipoint radio link designed to connect the 85 muon counters or subscribers to two coordinators located at the Coihueco fluorescence detector building. The link provides TCP/IP remote access to the scintillator modules through router boards installed on each of the surface detectors of AMIGA. This setup provides a flexible LAN configuration for each muon counter connected to a WAN that links all the data generated by the muon counters and the surface detectors to the Central Data Acquisition System, or CDAS, at the observatory campus. We present the design parameters, the proposed telecommunications solution and the laboratory and field tests proposed to guarantee its functioning for the whole data traffic generated between each surface detector and muon counter in the AMIGA array and the CDAS

  2. Telecommunications in South Africa: Governance of who is actually regulating?

    Directory of Open Access Journals (Sweden)

    L-F Pau

    2013-09-01

    Full Text Available Although the Republic of South Africa telecommunications market is a maturing one with a large customer base to serve, it has been repeatedly been observed over the past few years that many good intentions were formulated in the regulatory sphere with sometimes poor outcomes and unclear governance. A number of surprising observations have been made on the outcomes, the delays or other process related events linked to regulatory measures. The paper thus researches first, from a governance point of view, who is actually regulating the telecommunications industry; it identifies next opportunities and bottlenecks whereby a change might happen to reach the expected outcomes. A political economy methodology is taken, backed up by extensive field work over 2010 and 2011, leading to a web of conjectures providing answers to the first question, based on an extensive analysis of key stakeholders goals, positions and interactions. Finally, a number of measures are proposed to improve the governance, regulatory impact and efficiency, and evolve the South African telecommunications eco-system.

A typical Mars exploration case is defined, and support approaches comparing microwave and optical frequency performance for both local in situ and Mars-earth links are described. Optical telecommunication and navigation technology development opportunities in a Mars exploration program are also identified. A local Mars system telecommunication relay and navigation capability for service support of all Mars missions has been proposed as part of an overall solar system communications network. The effects of light-time delay and occultations on real-time mission decision-making are discussed; the availability of increased local mass data storage may be more important than increasing peak data rates to earth. The long-term frequency use plan will most likely include a mix of microwave, millimeter-wave and optical link capabilities to meet a variety of deep space mission needs.

    The use of photovoltaic systems as a stand-alone power supply in Libyan telecommunication networks has been in use since 1980. It was proved that PV generators are reliable and cost effective in this type of applications in comparison with diesel generators. In Libya about 100 photovoltaic systems were put into work to supply electricity for repeater stations instead of diesel generators, these PV systems proved to be reliable, very low or no communication stops, and and more economical in comparison with stations running by diesel generators, a wide knowledge of experience has been built of using photovoltaic systems in this applications. This paper is focusing on the role of stand-alone PV systems in communication networks of Libya, as a stand alone power source for telecommunication repeater stations. We will evaluate some of these systems after ten years of work, discuss the past experience, their reliability, and running cost, Stand-alone systems can be used in telecommunication networks, and in general the experienced advantages of using PV solar generators can be summarized as low running cost, high reliability, fewer services visits,, low maintenance cost, less number of thefts, no communication stops.(Author)

    Full Text Available Guaranteed selected quality of telecommunication service and wide area coverage are typical requirements of the ITS (Intelligent Transport Systems applications. Extensive range of wireless data services with reasonable coverage is provided by public wireless services operators, however, mostly no guaranteed relevant range of quality and security is available. ITS services require cost-effectively solution which can be resolved by combination of the "core" public solution with the other public as well as private services where and when it is needed. Such approach requires implementation of the relevant flexible system architecture supported by the efficient decision processes. ITS specific service security requirements would not underestimated, as well. Special situation is identified in case of the C2I (Car to Infrastructure and C2C (Car to Car communication namely if the vehicle on board unit is interconnected with the vehicle CAN (Controlled Area Network based network. Such configurations significantly increase potential of dangerous intruders´ attacks. Probability of the critical hazards appearances grows if the ITS data are accessible in the wide area networks. That is also the main reason why relevant telecommunications security support is understood as one of the crucial part of the ITS telecommunications solution.

    Full Text Available The challenge in the field of multimedia telecommunications is an attempt to integrate texts, sound, images and videos coherently and consistently and to ensure simplicity and interactivity of operation. In order to make the proposed multimedia applications acceptable to end-users, the quality of transmission through the network and message presentation should have special attention. The main aims of this paper are the introduction to the communication channel with its basic elements, a detailed description of the information source and the presentation of possible approaches to the analysis of the telecommunication channel. Introduction In the age of mass application of various communication means, end-users of telecommunication channel elements rarely pay attention to the processes taking place in everyday communication and the elements presented in the channel. In order to discuss all the factors that influence the establishment and maintenance of the links, this paper will explain the basic elements of telecommunication channels. Source Every object that generates messages to be transferred to a recipient is called the source of the message. Directors, writers, speakers, books, newspapers, various instruments (thermometer, barometer, ammeter, etc., computers, a man himself - these are all sources of various messages. In relation to facilities that generate messages, there are different sources of messages. All the messages that they generate belong to discrete or continuous modes of messages. Discrete messages can be presented with element sets, where elements can be considered through different values of observed messages. Each text message of arbitrary length, for example, is made of a finite number of elements - symbols (letters, numbers, punctuation marks, from the set of symbols called the alphabet message source. Continuous messages can be presented with an infinite number of sets of elements where elements can have different values of

    Environmental communication is becoming a sine qua non for companies which are more and more pressed by the need to reinforce communication with interested parties: environmental groups, local communities, local and national authorities, employees, share-holders, banks, insurance companies, customers and consumers. Reliable environmental information, just like economical and property data, is now required during both company take-over and financing, and in some cases it can affect insurance premiums. In fact, environmental guarantees are more and more often required because breaching environmental regulations can entail legal sanctions going as far as suspension of business. There now also Green investment funds that engage their resources only against specific environmental guarantees on the part of the companies that, before being selected for the investment, are submitted to rather accurate questionnaires by the investment manager [it

    Chiprianov, Vanea; Kermarrec, Yvon; Alff, Patrick D.

    Present day Telecommunications market imposes a short concept-to-market time for service providers. To reduce it, we propose a computer-aided, model-driven, service-specific tool, with support for collaborative work and for checking properties on models. We started by defining a prototype of the Meta-model (MM) of the service domain. Using this prototype, we defined a simple graphical modeling language specific for service designers. We are currently enlarging the MM of the domain using model transformations from Network Abstractions Layers (NALs). In the future, we will investigate approaches to ensure the support for collaborative work and for checking properties on models.

    Full Text Available Todays situations force telecomunication company to continuously evaluate, select and prioritize its product portfolio in order to determine the strategically important products. An analysis of critical success factors that determine product’s strategic importance acts as a good introduction to review and manage the product portfolio as well as to seek ways to develop the product. To achieve this, the company is required to have good alliances and collaborations between departments, develop a clear focus and seek innovative ways of doing business, particularly between marketing and product divisions. This study analyzed the alignment between product and marketing divisions of a telecommunication company in Indonesia, in determining the company’s strategic products. The results indicated that both divisions agreed on using financial performance and revenue as the most important criteria and sub-criteria for identifying strategic product. However, the divisions also faced some different visions in selecting alternative criteria. The Product divisions were more focused on technical spesification of product, while the Marketing division were more oriented on customer and market conditions. The study reported the consequences of these difference in practice.

    The German Telecommunications Satellite (DFS) Program is to provide telecommunications service for high data rate transmission of text and video data to the Federal Republic of Germany within the 11-14 GHz and 20-30 GHz bands. The space segment of this program is composed of three satellites, DFS-1, DFS-2, and DFS-3, which will be located at 23.5 degrees E longitude of the geostationary orbit. The DFS will be launched from the Center Spatial Guyanis in French Giana on an Ariane launch vehicle. The mission follows the typical injection sequence: parking orbit, transfer orbit, and earth orbit. Attitude maneuvers will be performed to orient the spacecraft prior to Apogee Kick Motor (AKM) firing. After AKM firing, drift phase orbital and attitude maneuvers will be performed to place the spacecraft in its final geostationary position. The Deep Space Network (DSN) will support the transfer and drift orbit mission phases. Information is presented in tabular form for the following areas: DSN support, compatibility testing, frequency assignments, telemetry, command, and tracking support responsibilities.

    2017-12-01

    The article is devoted to the study of the impact of the information economy on the formation of the middle class. The paper identifies factors contributing to the increase in the share of the middle class in the transition to the information economy. The positive synergetic influence of telecommunication technologies on the formation of the middle class is considered through a possibility of using virtual spaces for labor and educational activities, a possibility of obtaining high returns in the form of dividends on intellectual capital, a qualitative change in the structure of needs, an access to new types of information services, etc. Authors develop a complex model of research of the middle class in the information economy, differing from those available using an expanded list of criteria. In addition to such widely used criteria as income level, level of education and self-identification, the criterion "degree of involvement in the information society" was introduced. The study substantiates that the transition to the information economy made an access to information and communication technologies one of the most significant criteria for social differentiation of society. On the basis of the model, an econometric estimate of the middle class has been carried out, which makes it possible to reveal the share of the middle class in modern society, dynamics of its development, as well as multicollinearity between spending on education, the Gini coefficient, access to information and telecommunication technologies and the size of the middle class.

    2000-09-01

    The Secretariat of the Pacific Community (SPC) has made strenuous efforts to address communication imperatives for its programme delivery to its member countries. Initially, it used the Internet to assist in programme delivery. However, the low availability and high costs of telecommunications in Noumea and Suva hampered these efforts. The use of PACNET (the communications service of the Pacific Public Health Surveillance Network) was very successful but restricted by communication capabilities and lack of connectivity. In 1998 the capacity was limited to 28.8 kilobytes per second (kbps) in Noumea and 1.9 kbps in Suva with no possibility of obtaining additional capacity at affordable costs through the commercial telecommunications carriers. The ComET project has now installed 7.2 metre antenna and associated equipment at each of the Secretariat's offices in Noumea and Suva. This allows 24 hour per day access to the PAS2 satellite for high speed transmission of voice, data and video traffic. Connection to the Offratel premises in Nouville via the Celeris high speed backbone operated by OPT has linked this to the internet and thereby to member countries and territories, and the rest of the world. The ComET project began transmission in March 2000 and has addressed communication problems, and thereby improved the SPC's programme delivery (examples given in this paper) to it's members at affordable costs within the Secretariats existing budget.

    Telecommunications today are important factors in economic and social progress. The last decades of the 20th century and the early years of the 21st have been characterized as the Information Age. Telecommunications, the movement of information through distances, is absolutely critical to the economic and military survival of nations. This thesis is an attempt to predict the future of telecommunications, by studying and analyzing the past and present. First it examines the meaning of telecommunications today and some basics of information transmission. The current status of telecommunications is then presented, by examining the regional profiles as they are divided by the International Telecommunications Union. A number of statistical studies are given, which present a thorough picture of current world telecommunications. In an effort to predict future industry trends, the competition among the three largest telecommunications markets, U.S.A., Japan and the European Community, is also considered by looking at their present telecommunications industry, the efforts they make to improve their technology, and their plans for future investment. Finally, some major technological trends including BISDN, the use of fiber technology in the communications loop, and the use of solitons are examined. The new Metropolitan Area Network Protocol, FDDI-2 is also reviewed.

    The trends and factors currently emerging are likely to have significant influence on the way the upstream oil and gas industry evolves in the coming decade. This paper discusses how these trends might influence events in the 1990s, particularly how they might influence relationships between host countries and companies in the oil industry. State owned companies will dominate the industry in resource terms. These statcos fall into three groups: a small group of technically able, financially sound, well-managed companies; a group of consumer statcos that have limited domestic production but significant domestic demand; a large group that are finding it difficult to maintain their production facilities in good standing to maximize recovery from their resources. This paper describes the future private sector as consisting of the Surviving Sisters and smaller, private companies very active in the upstream. How will these various players behave in the years to come? Conventional activity in the upstream will continue as companies seek to optimize their upstream portfolios

    Full Text Available The concepts of spatial-division multiplexing (SDM technology were first proposed in the telecommunications industry as an indispensable solution to reduce the cost-per-bit of optical fiber transmission. Recently, such spatial channels and modes have been applied in optical sensing applications where the returned echo is analyzed for the collection of essential environmental information. The key advantages of implementing SDM techniques in optical measurement systems include the multi-parameter discriminative capability and accuracy improvement. In this paper, to help readers without a telecommunication background better understand how the SDM-based sensing systems can be incorporated, the crucial components of SDM techniques, such as laser beam shaping, mode generation and conversion, multimode or multicore elements using special fibers and multiplexers are introduced, along with the recent developments in SDM amplifiers, opto-electronic sources and detection units of sensing systems.

  7. Companies as "Cyborgs"?

    Thompson, Grahame

    This paper investigates the legal and commercial consequences of companies being considered as both an entity and a person in law – hence the notion of ‘cyborg’ in its title. It concentrates upon legal personhood and relates this particular feature to the issue of corporate citizenship. In turn...... corporate citizenship provides a link to considering the political role of companies, since in claiming citizenship they are implicitly at least claiming a particular set of political rights consequent upon that status, and announcing a particular politically constrained context associated...... with their operational characteristics. But what would be involved in granting companies full citizenship rights in the image of natural person citizenship? The paper explores this issue in connection to the differences between corporate social responsibility and an earlier idea of the socially responsible corporation...

    Full Text Available In recent years, some of China’s leading firms have made headlines with their European expansion, by either opening new facilities or by acquiring or merging with significant enterprises in Europe. The goal of this paper is to contribute to the existing literature by examining Chinese enterprises expanding into Switzerland. The study also allows some conclusions for Chinese companies entering Central and Eastern Europe. We analyze via interviews the motivations of Chinese companies to expand into Switzerland as well as their behavior and the impediments in their internationalization process. Our findings show that Chinese companies fail to take advantage of certain benefits of western economies (such as open information and stable rule of law. To move forward efficiently, they should develop competence in dealing systematically with readily available market information, building professional networks that recognize a separation between business life and personal life, and managing their Chinese and foreign employees in the foreign cultural environment.

  10. RESTRUCTURING COMPANIES UNDER CRISIS

    Directory of Open Access Journals (Sweden)

    Full Text Available Nobody is planning to fail, but many companies are failing because of lack of planning. Real business experience showed during the years that crisis can be prevented, avoided or limited. If detected in time, the risks associated with the crisis can be mitigated and the effects can be diminished, with the condition that the actions required are done fast, in a sharp and accurate manner. When it comes, a crisis brings an intense level of pressure and under these conditions there is no time or room for mistakes. Delays, losing focus and lack of planning will bring a company one step away from failure. The right way to deal with crisis, if required measures are not done in time, is to minimize the losses and reposition in the best way possible. Analysing the success stories of some of the biggest and strongest companies in the world, led to an important conclusion: the majority of these companies were in the situation to face huge crises which threatened their ability to survive in certain moments, on their way to success. With the right planning and by setting a proper organisational structure, the negative aspects of the crisis can be turned into benefits and opportunities for the company. The most critical challenge for management is to assess the level of exposure to risk of the company and identify the key points to focus on in order to overcome the crisis and create value. In order to set up a strong plan in dealing with crisis, a business organisation needs reliable, efficient and effective tools and this is what this article is all about.

    Full Text Available A company’s manager has to create and maintain a healthy internal control system. An efficient internal control system implies the implementation in the company of risk management. Each company, but also each individual, who tries to attain certain objectives, establishes the activities which lead to the achievement of goals and, at the same time, tries to identify as many “threats” as possible, in order to take the necessary measures to eliminate them. Thus, even if one is not familiar with the concepts of risk and risk management, one acts, consciously or not, for that purpose.

    With the current popularity of information and telecommunication technologies, more and more farmers recognize the important role of information. The urgent need for Chinese farmers is how to make use of information to get rich. Contrast in the newspapers, television, radio and other traditional media, mobile information services have unmatched advantages, such as wide spread in very low cost, spread source of widely dispersed, and diverse forms of communication, simple and easy to operate, with strong participatory and interactive, and so on. The paper proposes that Mobile operators can supply different information in accordance with personalized demands of farmers with various agencies, such as government departments, supply and marketing cooperatives, hospitals, banks, veterinary clinics, agricultural stations. They can unite to supply a number of convenience people, rich people, and love for the people's business through the message, voice, WAP and other forms to meet the needs of farmers. Besides, the paper points out that those farmers can order information on personalized service.

    The Phoenix Lander, first of NASA's Mars Scout missions, arrived at the Red Planet on May 25, 2008. From the moment the lander separated from its interplanetary cruise stage shortly before entry, the spacecraft could no longer communicate directly with Earth, and was instead entirely dependent on UHF relay communications via an international network of orbiting Mars spacecraft, including NASA's 2001 Mars Odyssey (ODY) and Mars Reconnaissance Orbiter (MRO) spacecraft, as well as ESA's Mars Express (MEX) spacecraft. All three orbiters captured critical event telemetry and/or tracking data during Phoenix Entry, Descent and Landing. During the Phoenix surface mission, ODY and MRO provided command and telemetry services, far surpassing the original data return requirements. The availability of MEX as a backup relay asset enhanced the robustness of the surface relay plan. In addition to telecommunications services, Doppler tracking observables acquired on the UHF link yielded an accurate position for the Phoenix landing site.

    The distribution of high spectral purity reference signals over optical fibre in future telecommunication satellite payloads is presented. Several types of applications are considered, including the distribution of a reference frequency at 10 MHz (Ultra-Stable Reference Oscillator) as well as the distribution of a radiofrequency oscillator around 800 MHz (Master Local Oscillator). The results of both experimental and theoretical studies are reported. In order to meet phase noise requirements for the USRO distribution, the use of an optimised receiver circuit based on an optically synchronised oscillator is investigated. Finally, the optical distribution of microwave local oscillators at frequencies exceeding 20 GHz is described. Such a scheme paves the way to more advanced sub-systems involving optical frequency-mixing and optical transmission of microwave signals, with applications to multiple-beam active antennas.

    2000-01-01

    The quality of a telecommunication voice service is largely inftuenced by the quality of the transmission system. Nevertheless, the analysis, synthesis and prediction of quality should take into account its multidimensional aspects. Quality can be regarded as a point where the perceived characteristics and the desired or expected ones meet. A schematic is presented which classifies different entities which contribute to the quality of a service, taking into account conversational, user as weIl as service related contributions. Starting from this concept, perceptively relevant constituents of speech communication quality are identified. The perceptive factors result from ele­ ments of the transmission configuration. A simulation model is developed and implemented which allows the most relevant parameters of traditional trans­ mission configurations to be manipulated, in real time and for the conversation situation. Inputs into the simulation are instrumentally measurable quality elements commonly used in tra...

    2016-01-01

    Full Text Available This paper deals with network competition and provides empirical analysis of market concentration, network and call externalities, access pricing, price discrimination and switching costs in Serbian mobile phone telecommunications market. It is shown that network externalities governed the expansion of this market until 2008. Upon entry of VIP incumbents didn't engage in predatory behaviour towards entrant aiming to benefit from locked- in users. The policy of mobile phone number portability reduced on-net prices and substantially increased consumer's surplus. In contrast to some previous research, this policy was pro-competitive in Serbia. We have also determined that users of the network with the largest market share benefit the most from call externalities. Finally, one network does not price discriminate between outgoing and incoming roaming calls, which implies that users of this network have higher level pecuniary externalities in roaming compared to users of price discriminating networks.

    CommAspen is a new agent-based model for simulating the interdependent effects of market decisions and disruptions in the telecommunications infrastructure on other critical infrastructures in the U.S. economy such as banking and finance, and electric power. CommAspen extends and modifies the capabilities of Aspen-EE, an agent-based model previously developed by Sandia National Laboratories to analyze the interdependencies between the electric power system and other critical infrastructures. CommAspen has been tested on a series of scenarios in which the communications network has been disrupted, due to congestion and outages. Analysis of the scenario results indicates that communications networks simulated by the model behave as their counterparts do in the real world. Results also show that the model could be used to analyze the economic impact of communications congestion and outages.

    This paper describes a remote monitoring system that can be set up in an operating center to monitor the state of valve regulated lead acid batteries (VRLA) used as a backup power supply for telecommunications. This system has a battery voltage monitoring function, a lifetime prediction function based on ambient temperature, and a discharge circuit diagnosis function. In addition, the system can be equipped with an internal resistance measurement function and an electrolyte leakage detection function to further insure power-supply reliability. Various states of batteries observed with the system are transmitted to the remote operating center by a remote monitoring function. This function enables obtaining immediate information about the condition of batteries and helps to avoid unexpected failures. (author)

    Examination of the accident records from the telecommunication industry covering some 100 000 engineers over a 12-month period showed that 25% of accidents resulting in more than three days' sick leave gave rise to back injuries. Handling accidents and falls accounted for 65% of three-day-plus accidents; handling accidents alone gave rise to 65% of back injuries. The absolute numbers of accidents have been compared with the total population of engineers to estimate the effects of age or occupation on levels of hazard; certain occupations constituting 33% of the engineers' population suffered 70% of all three-day-plus accidents. Accidents occurred most frequently in the group aged from 31 to 48 years. Other significant factors affecting the occurrence of accidents were time of year and duty experience of the workers.

    Today, people are making use of several devices for communications, for accessing multi-media content services, for data/information retrieving, for processing, computing, etc.: examples are laptops, PDAs, mobile phones, digital cameras, mp3 players, smart cards and smart appliances. One of the most attracting service scenarios for future Telecommunications and Internet is the one where people will be able to browse any object in the environment they live: communications, sensing and processing of data and services will be highly pervasive. In this vision, people, machines, artifacts and the surrounding space will create a kind of computational environment and, at the same time, the interfaces to the network resources. A challenging technological issue will be interconnection and management of heterogeneous systems and a huge amount of small devices tied together in networks of networks. Moreover, future network and service infrastructures should be able to provide Users and Application Developers (at different levels, e.g., residential Users but also SMEs, LEs, ASPs/Web2.0 Service roviders, ISPs, Content Providers, etc.) with the most appropriate "environment" according to their context and specific needs. Operators must be ready to manage such level of complication enabling their latforms with technological advanced allowing network and services self-supervision and self-adaptation capabilities. Autonomic software solutions, enhanced with innovative bio-inspired mechanisms and algorithms, are promising areas of long term research to face such challenges. This chapter proposes a bio-inspired autonomic middleware capable of leveraging the assets of the underlying network infrastructure whilst, at the same time, supporting the development of future Telecommunications and Internet Ecosystems.

We use shadow mask technique on an n-i Schottky photodiode structure with QDs to excite a single QD resonantly. Coherent pulse excitation is realized in two types of setups utilizing (i) an optical parametric oscillator and (ii) a stable semiconductor laser diode. In both setups we observe the biexcitonic PC peaks induced by a coherent two-photon process. Especially in the latter setups, the narrower pulse linewidth in energy provides a clearer biexcitonic PC peak because of reduced unwanted excitation. We estimate the binding energy ΔE B of our telecom-band biexciton to be 0.9 meV from the splitting between excitonic and biexcitonic resonances. The result suggests our telecom-band exciton-biexciton system is a good candidate for the building block of fiber-based controlled-rotation quantum logic operation.
